HOW TO USE THIS MANUAL


1) Read Section I Introduction.

2) Read Section II C-NETT Characteristics.

3) Install C-NETT after reading Appendix A.

4) Play with C-NETT using DEMO.DAT as input data.

5) Read other sections of the manual as needed.


WARNING:

As with any software, it is possible with C-NETT to produce
misleading reports. Input garbage will produce output garbage.
Automated systems are an aid. They do not replace the human
thought process. The user must add a reasonableness check of his
own to the results of any system.

C-NETT is a new product and it must be assumed that, despite
considerable testing, there may be bugs in the code. Any problems
which come to the attention of the developer will be fixed and
the fixes installed in updates. These updates will be available
to owners of copies of C-NETT at a nominal charge.

If you produce a C-NETT product which shows you can complete
a project in six months and it really will take a year, and you
misbid as a result, that is YOUR problem. If a bug in C-NETT was
involved and we are informed, the fix will be in the next update.
Note, however, that any bugs that may be in C-NETT would more
likely result in flawed graphics or aborted processes, rather
than misleading reports. In any case, OUR LIABILITY IS LIMITED
TO SOFTWARE REPLACEMENT AT NOMINAL CHARGE. If this is
unacceptable to you, don't buy the software.

The purchaser of C-NETT software buys the right to use the
software on one computer only. The purchaser has no right to
provide copies to others under any conditions. A backup copy can
and should be made. This software is not copy protected.
However, each sold copy of C-NETT has a unique copy number which
is marked on the distribution disks and written into the
software.

I. Introduction

An automated system doesn't have to be complex and difficult
to use in order to be powerful and effective. Several word
processing systems have proven this point - providing easy-to-use
systems as powerful as their more complex counterparts. Ease of
use, borne of a straight-forward, well-organized approach, has
actually made them more effective.

C-NETT proves this point again in Project Management. With
C-NETT, effective design not only makes the system easier to use,
but also makes the system products more easily understood. Ease
of use is enhanced by a user friendly menu and screen entry
system providing access to and control over a well-organized set
of system functions and products. The cornerstone of effective
communication through the products is the C-NETT use of an
hierarchical task numbering system. The system recognizes
hierarchical numbering (e.g. Task A1 is a subtask of Task A.) and
provides a summary capability based upon it. Up to eight task
levels are available. The user can select sets of varying level
summary and detail Gantt charts which very effectively integrate
views of the big picture with those of intermediate and detail
levels. With the use of hierarchical numbering, reviewers of
C-NETT products have an immediate understanding of task
relationships. With other systems which either do not support
tiering or have a hidden tier specification, there can be
continuing confusion.

Flexibility in network construction is another key element
of the C-NETT approach. C-NETT establishes the start of a task
as the point at which all start requirements are met. These
requirements can be any combination of start or end dates and
predecessor requirements. Predecessor requirements may include
head-to-tail relationships and requirements for some number of
days past the start of the predecessor. There is no limit on the
number of predecessors. Whereas, other systems force the user to
tie the network into a single critical task, C-NETT allows the
designation of any number of critical tasks. These tasks may
either be declared as critical (zero slack) or be given a
deadline date. All tasks in the predecessor chain of one or more
critical tasks are assigned the shortest applicable slack.

C-NETT provides Gantt Charts and Network Diagrams on-screen,
on dot-matrix printer, and for pen plotters in three different
protocols. All are high resolution graphical products as opposed
to the character space resolution of many systems. On-screen
products provide quick response displays. Dot-Matrix products
provide 120 dot per inch high quality hard copy products. Pen
plot versions are publication quality products. All products can
be tailored by the user.

C-NETT schedules are essentially unlimited in period. Any
of three calendar types may be used for a network: all days, five
day work weeks, or five day work weeks excluding user selected
holidays.

1





Extensive error checking and on-screen help is provided by
the system. Error messages are provided for illegal entries such
as off-calendar dates. The entry of a ? generally results in the
display of a help screen for that input.

In summary, C-NETT provides a user friendly, flexible,
powerful system with high quality products at a low price.



II. C-NETT Characteristics

C-NETT is designed to provide a very powerful and effective
automated project management support system to the user. The
power of the system includes automated tier level summaries,
flexible task interfacing, and multiple critical task
specification working on a fast schedule networking algorithm
capable of handling 2000 tasks. System effectiveness is enhanced
by a friendly error detecting user interface, easy to use data
entry editors, and a set of user configurable products.

A. Task Numbering

C-NETT allows for and encourages, but does not require, the
use of hierarchial task numbering (and/or lettering). When
properly applied, such numbering can provide the user automated
tier level summary capabilities.

C-NETT task numbering rules are as follows:
1. Up to eight letters and/or numbers may be used.
2. Task numbers are case sensitive.
3. Task numbers should be left justified wherever entered.
4. Task number hierarchy series (e.g. A,A1,A2,A2x,A2y or
x,xA,xA1,xA2...)is recognized by C-NETT and can be used
to provide structure for summary capabilities in
products such as Gantt charts.

B. Setting Up Summary Tiers

Normally, a summary level of anything has as its attributes
only the composite of those of its subordinates. The
corresponding situation with C-NETT task structure, is for
schedule attributes to be assigned to non-summary level tasks
only. Note that this is encouraged but not required by C-NETT,
however.

The attribute (aka detail) level can and typically does vary
over the network. For example, the structure A,A1,A11,A12,A2,B
would have schedule attributes assigned to tasks A11,A12,A2 and
B. A Level 1 Summary Gantt chart would have two lines - Task A
(a composite of A11,A12, and A2) and Task B representing itself.
A Level 2 chart would have lines for A (title line without a task
bar), A1 (composite of A11 and A12), A2 representing itself, and
B again representing itself. (Note that the level is the number
of characters counting from the left of the task number.)

2






C. Automated Summary

C-NETT automated summary capability allows a structured
approach to schedule management. Using this capability which is
based upon the hierarchical task numbering, the user can easily
command the production of detail and varying level summary charts
and reports to present a cohesive view of the project or program.

The relationship of tasks and subtasks is automatically
communicated in a set of C-NETT products. That is, it is
immediately evident to all that attributes reported for a higher
level task are composites of the attributes of its subtasks.
(e.g. For the series B,B1,B11,B12,B2,C,C1,C2; a Gantt line for B
includes those of B1 and B2. A B1 attribute is the combination of
those of B11 and B12 etc.) Such effective communication is not
available when, as in other systems, the hierarchy is specified
in a hidden auxilliary data set.

D. Flexible Task Interfacing

C-NETT provides an extremely flexible system for the
schedule interface of tasks. A task start may be specified by
any, all, or none of the following:
1. The required completion of any number of tasks.
2. The passage of any specified number of days from the
start of any number of tasks.
3. A start or end date or both.
4. A task duration or span.
With multiple start specifications, that causing the latest start
rules.

E. Critical Task(s) Specification

The user may specify an unlimited number of tasks as
critical. Such a task may be caused to be critical (have zero
slack) whatever its start/end date may be. Or, a task may be
given a deadline date. The schedule networking algorithm assigns
critical end dates (and corresponding critical slack) to other
tasks which are in the predecessor chain of one or more of the
critical tasks.

F. Schedule Networking Algorithm

The schedule networking algorithm reconciles the task
specifications (task interfaces and critical task specifications)
into a schedule for all tasks. Task schedules include start and
end dates and a critical end date. For tasks which are not in
the predecessor chain of a task designated critical, the critical
end date is indicated as indefinite and its critical slack is a
large number of days.

3








This algorithm provides extensive error detection with
corresponding error messages. Of special note, it detects task
interface loops and reports specifically what interfaces are
involved in the loop. (A loop is an unresolvable situation in
which a task appears in its own predecessor chain.)

G. C-NETT User Interface

The C-NETT user operates in a menu and entry form system.
Extensive error checking is provided. Commands and selections are
generally not case sensitive. Entry of a "?" where a command or
selection is required will result in user help appearing on the
screen (in those situations where there can possibly be doubt).

System friendliness is such that this manual should get
limited use. Just enter "CNETT" at the DOS prompt and let the
system and your intuition be the guide. Use the manual primarily
for explaining input data.

III. C-NETT Operation

In this section we will present a quick overview of the
C-NETT Main Menu citing the purpose and function of each of the
menu options. Detailed review of each will be provided in
Sections IV through XI.

After installing the system (See Appendix A. for procedures to
install C-NETT.) set the default directory to the CNETT
subdirectory and type CNETT. This brings up the C-NETT Main Menu
which has the following elements:

NETWORK DATA ENTRY
A) FULL SCREEN EDITOR
B) LINE EDITOR
NETWORK COMPUTATION
C)
ON-SCREEN DISPLAYS
D) GANTT CHART
E) NETWORK DIAGRAM
DOT MATRIX PRODUCTS
F) GANTT CHART
G) NETWORK DIAGRAM
H) TABULAR REPORT
PEN PLOT PRODUCTS
I) GANTT CHART
J) NETWORK DIAGRAM
SET/CHANGE SYSTEM DEFAULTS
K) COMPUTED FILE USED FOR PRODUCTS
L) PLOTTER/PRINTER/VIDEO SELECTIONS

4






Selections A and B are editors which support the preparation
of network specification data files. These are the files in
which the user defines tasks, predecessor relationships, start
dates, end dates, critical deadlines etc. Each of these editors
provides the same general capability. It is a matter of personal
preference which the user may use. A user may find that he
prefers one for original data input and the other for update.

Selection A, the full screen editor, places all of the
information for a task in one entry screen as a set of labeled
entry fields. Field movement, task to task paging, save, task
insert etc. are provided via a single keystroke.

Task data is stored in the form of records which contain
selected types of information. There are four record types which
make up the complete set of task data. Additionally, a header
record is used to make general selections for the data set. (See
Appendix A for a complete data description.) Selection B, the
line editor, operates at the record rather than task level. The
user steps through the data file altering, adding or deleting
records. Entry screens similar to those of the full screen
editor are provided for record data entry.

Selection C reads the data file created by the editors and
creates a computed network file.

Selections D through J read the computed network file
(created by C) and produce the On-screen, Dot-Matrix and Pen Plot
products. Dot-Matrix and Pen Plot products are produced in the
form of printable files. The MS-DOS PRINT command is used to
send them to a printer or plotter (e.g. PRINT FILENM.TYP).

C-NETT assumes that the user wants to use the last computed
network file for products unless told otherwise. The user tells
otherwise via Selection K. He is prompted for an alternative
computed file. A null entry at this point results in each
product program prompting for the desired computed file.

Selection L provides a means of selecting plotter protocol,
dot-matrix graphics procedures, and video mode. These selections
are made and changed by this facility.

Figure III-1 presents a schematic of C-NETT operation
illustrating the above discussion. Additionally, this schematic
shows the filenaming conventions for input data and computed
files. Input data files have a filetype of .DAT while computed
files are of filetype .CMP.

IV. Full Screen Editor A)

The C-NETT Full Screen Editor presents all of the input data
for a task on a single screen. Field control functions are
provided to conveniently move from field to field and make
changes. Error checking is provided. If an error is detected, a
message is placed at the bottom of the screen and the cursor will
not leave that field until a correct entry is made or the field
is blank. The following functions are provided:
KEY ACTION
PAGE DOWN Advances to the next task. The first task follows
the last task.
PAGE UP Backup to previous task. Last task precedes first
task.
LEFT ARROW Moves one character space to left within field.
From first space in field goes to previous field.
RIGHT ARROW Moves one character space to right within field.
From last space in field moves to next field.
UP ARROW Moves to field above.
DOWN ARROW Moves to field below.
TAB Moves to next field
ENTER " " " "
INS Clears space for character insertion.
DEL Deletes a character.

F1 Toggles Task Insert Mode on or off. While on, a
series of tasks may be inserted after the last
task displayed before entering this mode. Each
task is entered and the screen cleared by F2
(save).
F2 Save the changes made. NO CHANGES WILL BE ENTERED
WITHOUT PRESSING F2!
F3 Delete task.
F4 Search for WBS#. Enter the WBS# into the WBS#
field of the current task page and press F4.
ESC Leave the editor. The user will be asked to enter
a filename for the changed file. A null entry
will result (after user confirmation) in the
changes being discarded. Note that the original
file remains.

A screen for updating the file header record is displayed
upon the opening of a data file. This screen operates similar to
the task screen. The ARROW keys, TAB, ENTER, and ESC are active.
The remainder of those listed above are not. ESC saves the
changes made and turns to task change mode.

CAUTION: This editor has a limited (albeit large) number of
spaces for predecessors of a task (21 total - 13 head-to-tail and
8 partial). If changes are made to tasks which exceed these
limits additional predecessors not displayed will be deleted.
The Line Editor has no such limitation.

7






V. Line Editor B)

The Line Editor treats the C-NETT Input Data Set as a series
of records grouped as tasks. It allows the user to make changes,
additions, and deletions on the record basis rather than on the
task basis as with the Full Screen Editor. Often a user will
prefer to print the data file (It is stored and will be printed
as a series of records.), mark changes and then step through the
records in the Line Editor making those changes.
Entries/changes for a record are made on a field entry screen
functionally similar to the Full Screen Editor.

The following entries control operations:

ENTRY ACTION
S Search for WBS#. The user is prompted for
the WBS#.
B Backup one record.
D Delete the current record.
C Change this record.
H Update the header record.
1,2,3, or 4 Insert a record of this type after the current
record.
ENTER Advance one record.
F Advance one screen (24 lines).
P Enter Progress Data Entry System. This system
expedites the entry of progress data. It
displays only the WBS#, Progress data type
(T or S) and the number of days. Entry of
a letter and/or number (either or both in
either order) will be accepted. In this mode,
the entry of an A provides a function similar
the S above (WBS# search). ENTER advances a
record. X exits the Progress System.
R Displays a screen describing field entries
by record.
? Lists the entries described here.
X Exit form the Line Editor. As with the Full
Screen Editor, the user is prompted for
a filename into which to write the the
updated data file. A null entry results
(after confirmation) in discarding changes.

SCREEN ENTRY COMMANDS:
ESC Save entries and leave the record screen.
ARROWS Within field and between field cursor moves
as with the Full Screen Editor.
TAB, ENTER Move to next field.

VI. Network Computation - C)

C-NETT uses a very efficient algorithm to provide a very
quick computation of the network from the input data set prepared
by the editors.

Extensive error checking is done on the data. This includes
a recheck of dates and integer ranges, check for the existence of
predecessors, and detection of predecessor loops. The latter is
an unresolvable condition in which a task appears in its own
predecessor chain. In this case, a screen message lists all
predecessor-successor connections involved in the detected loop.
The user must remove the erroneous connection(s) before the
computation can be completed.

The output file receives the same name as the input data
file with a file type of .CMP as opposed to the .DAT file type of
the data file. If a computed file of the same name exists, an
altered name with a digit added is constructed and the user so
informed by screen message. Multiple computed files may be
maintained by user choice. The system uses the last computed
unless another is designated via selection K.

VII. Gantt Charts - D), F), & I)

C-NETT Gantt Charts (On-Screen, Dot-Matrix, and Pen Plot)
follow similar specification processes. Most users will navigate
the process without help but samples of system prompts are shown
and explained here.

Prompt:
1) WBS Order Hierarchy including Summary
2) Task-only with Multi-field Select and Sort
3) Exit

Discussion: Two types of charts are offered. The first lists
tasks in the order entered with higher level tasks included. Task
groups are selected as contiguous groups. This choice includes
WBS Level Summary charts. The second option allows a more
flexible selection of tasks. Higher level tasks are excluded.
Tasks may be ordered by start date.

Prompt:
M :P:C:S:
: :A: :R:R:U:
:T:N:O:O:T:M:

S:E:R:N:S:H:L:12345678901234567890123456789012


9






Discussion: Read the first 7 fields downward. The first four are
field selections on the chart. If you want a WBS field place an X
below it. (Same for the Title, Manager and Organization fields.)
For the display of progress information place an X in the fifth
space. For the placement of a marker at the critical end date of
each task, place an X in the sixth place. If a summary chart is
desired, place the number of the level desired (1-7) under SUM
LVL. Thirty-two spaces are allotted for a title which will
appear on each page of the chart.

Prompt:
WBS TIME WIDTH CPI
FIRST LAST START COMPL (IN) 10/
12345678 12345678 MMMYY MMMYY XXXX 17

Discussion: The first two fields are for the first and last
WBS#s to be included on the chart. Left justify! Next, start and
end dates (e.g.JAN89). Width of the dot-matrix chart can be
selected to the maximum width of the printer (e.g.12.5). 10 or 17
characters per inch print (Pica or compressed) can be selected.
(If no entries are made in the last two fields, a default of 7.2
inches and 17 CPI is invoked.

Prompt:
WBS TIME SIZE (IN) LINES
FIRST LAST START COMPL WDTH HGHT /PAGE
12345678 12345678 MMMYY MMMYY XXXX XXXX XX

Discussion: This specification for the Pen Plot Gantt provides
for the entry of width and height in inches (e.g. 14.5 8.5).
Letter size is selected in terms of number of lines per page.

Prompt:
Add to List Qualify List

A) All Tasks F) By WBS Group
B) By WBS Group G) By Manager
C) By Manager H) By Organization
D) By Organization I) By Time Slice
E) By Time Slice
P) Write the Chart
S) Sort by Start Time and Write

Discussion: This selection method is used for the second chart
type. The process starts with no tasks. Choices A through E add
selected groups to the list. Choices F through I qualify the
list by excluding tasks not meeting entered criteria. The chart
selection process is exited via P or S which call for original
entry order or order-of-task-start (known as Waterfall order).


10





VIII. Network Diagrams - E), G), & J)

C-NETT Network Diagrams (On-Screen, Dot-Matrix, and Pen
Plot) follow similar specification processes. Most users will
navigate the process without help but samples of system prompts
are shown and explained here.

Prompt:
TASK QUALIFICATION
1) BY WBS 2) ORG 3) TIME SLICE 4) SLACK
5) RESTART SELECTION 6) SELECTION COMPLETE

Discussion: Task selection for Network Diagrams begins with all
tasks. That list can be successively qualified by categories
reflected in 1 through 4 above.

Prompt:
Enter Plot Format:
1) Horizontal Flow
2) Vertical Flow (Single Line Box)
3) Vertical Flow (Double Line Box)
3
ENTER DESIRED LETTER SIZE
(IN HUNDREDTHS OF AN INCH WITH
MAX OF 100 e.g. 9)
8
THE PLOT WILL BE
13.4 INCHES LONG AND 7.8 INCHES HIGH
PROCEDE, RESCALE, OR ABORT? (P/R/A)

Discussion: This is used only with the Pen Plot Network Diagram.
The purpose of having alternative configurations is to facilitate
the fitting of a network diagram on a minimum number of plot
sheets. Entering an R to the last prompt will return to the Plot
Format choice. Samples of the three configurations are shown in
Section XII.






11








IX. Tabular Report - H)

Two report types are offered. The first (designated
Abbreviated) lists all tasks with WBS#, Title, Manager,
Organization, Start Date, End Date, Task Duration (Span), Slack
and days of progress. The second (Complete) additionally
includes similar listings for predecessors and successors with
each task. The predecessor and successor listings differ from
those of the parent task in that the Slack entry is replaced by
an entry designated "Gap". Gap is the period between the end of
a predecessor and the start of the parent task or the end of the
parent task and the start of the successor.


X. Set/Change Computed File - K)

C-NETT will use the last computed file produced for products
unless this option is used. With this, the user is prompted for
a desired replacement filename. That file will be used for
products until changed by this option or by the creation of a new
computed file. If a null entry is made at the prompt, the user
will be prompted for a computed file name with each product.

XI. Set/Change Plotter/Printer/Video -L)

This facility provides for the selection of plotter protocol
and limits, dot-matrix graphics commands, and video board
selection:
A. Three plotter protocols are available (AMPLOT II, Houston
Instruments or HPGL). Numerous plotters of other manufacture use
these same protocols.
B. Horizontal and vertical plotter limits are entered as two
numbers separated by a space or comma (e.g. 17,11 or 15.5 10.5).
C. Minimizing the size of graphics files can be accomplished
by spacing over blank portions of lines in character format. For
many printers there is no down side to this approach. For some,
the frequent switching from character to graphics modes and the
reverse causes the printer to slow down and stutter. For those
the "Expanded" files are recommended. They provide for
all-graphics lines where frequent switching is likely. The
"Expanded" files can be several times the size of the
non-expanded versions.
D. Monochrome graphics requires different handling than CGA,
EGA, and VGA. In addition to answering "Y" to the last question
under Selection L, the monochrome graphics driver QBHERC.COM must
be installed before running C-NETT on-screen displays. This is
done by typing QBHERC at the DOS prompt. The convenient method
is to add QBHERC to the AUTOEXEC.BAT file, which will cause this
driver to be installed when the computer boots.

12





XII. Sample C-NETT Products

Space does not permit a set of sample products which
reflects the variability allowed. All allow the selection of any
set of tasks. All except the Dot-Matrix Network Diagram and
On-screen products allow size selection. The plotted products
allow size and shape selection. Gantt charts allow extensive
field and notation selection in addition to summary level and
task order.

A. Dot-Matrix Gantt Charts

Figures XII-1 through XII-3 display the three primary
options: detail in WBS order, WBS summary, and selected detail
tasks in waterfall order. The following features are worth
noting:
1) The calendar displayed here is only six months. By user
choice, it could be any period up to 30 years. As the allotted
space per time decreases, the labels go successively to single
letters per month, to numbered calendar quarters, to 4-number
years, and to 2-number years.

2) Any or all of the WBS#, Title, Manager and Organization
fields can be displayed.

3) On the WBS ordered charts, higher level tasks are shown
without span lines. On the selected task chart, they are not.

4) The dark lines indicate progress. A dark line covering
the length of a task indicates that it is complete. On summary
charts (XII-2), best/worst case progress of the task group summed
is shown by the upper and lower lines respectively. The best case
is set to the latest progress date for an in-progress task. The
worst case is set at the earliest progress date.

5) The triangles represent the critical (latest complete)
date for the task. For a summary line, this notation is at the
point of the latest critical date for the summed group.

6) Note that all of the notation can be selected or not by
the user.

7) The width of the chart may be specified within printer
limits.

8) Pica (10 characters per inch) or compressed (17 CPI) may
be selected. The compressed print allows more space for the
calendar area.


13





B. Pen Plot Gantt Charts

Figures XII-4 and XII-5 display detail in WBS order and
selected detail tasks in waterfall order. As with the
dot-matrix, summary is also available. All of the feature
description with the dot-matrix Gantt (except 8)) applies equally
to the pen plot Gantt. Additionally, the following is unique to
the plotted version:
1) Any width and height within plotter limits may be
selected.
2) Letter size is selected by specifying the number of line
spaces per page.
3) When progress annotation is chosen, an as/of vertical line
is drawn.

4) Separate plot files are produced for each page. C-NETT
assigns the user chosen name and a succession of extensions
(.GP1, .GP2 ...).

C. Dot-Matrix Network Diagrams

Figure XII-6 shows a sample Dot-Matrix Network Diagram.
Showing the predecessor-successor relationships of selected
tasks, this product has the following features:
1) The task set to be displayed is selected based upon
combinations of the following criteria: WBS groups, time period,
task organization, and slack.
2) Tasks are ordered vertically by time and horizontally by
slack. Ordering by slack results in the most critical path being
on the right with other paths placed leftward in order of
criticality. In addition to more clearly displaying critical and
near critical paths, this arrangement results in fewer crossing
lines.

3) Days of slack is shown with each task WBS. If the task is
not in a path leading to a critical task, slack is indefinite and
is shown by ****.

D. Pen Plot Network Diagrams

Figures XII-7 through XXII-9 present the three
configurations of Pen Plot Network Diagrams. The three
configurations are offered to facilitate the fitting of the
diagrams on a minimum number of plot pages. Features described
for the dot-matrix version also apply here along with the
following:

1) Letter size is selectable. This with the configuration
choice is used by C-NETT to provide a plot size. These choices
may be altered by the user and successive new size calculations
made prior to committing to a plot construction.

2) As with the Pen Plot Gantt, separate files are written for
each plot page. C-NETT assigns the extension series NP1, Np2
....


17







E. Tabular Report

Figures XII-10 and XII-11 show the Abbreviated and Complete
Tabular Reports. The first has lines for each task. For higher
level task lines, the WBS#, Title, Manager, and Organization are
listed. For detail level tasks the start/end dates, slack and
days progress are listed. The complete report lists the
predecessors and successors with similar information. With the
predecessors and successors a "gap" is shown instead of slack.
Gap (often referred to an non-critical slack) is the number of
days separating that task from the parent task.


F. On-Screen Gantt Chart

This product is much the same as the dot-matrix and pen
plot versions. However, a number of items which are user
selected for the other products are preselected with this one.
The field selection is eliminated with the WBS# and Title being
shown. Progress and critical path marks are shown. The calendar
is set to cover the spans of the selected task set. Both WBS
order with summary and selected task are available. Figure
XII-12 depicts (via screen print and partial reconstruction) a
selected task version in waterfall order. Single keystroke
options are listed across the bottom of the screen:
1) Q=QUIT - Return to C-NETT Main Menu.
2) T=TOP - Show tasks starting from the top of the list.
3) P=PREV PAGE - Show the task group immediately
preceding.
4) N=NEXT - Show the next task group.
5) L=LINE MOVE - Move down the list a selected number of
tasks. The user is prompted for the number.
6) F=FIND - Move to and center the screen on a selected
WBS#. The user is prompted for the WBS#.

G. On-Screen Network Diagram

Again this screen version is much like its dot-matrix and
pen plot counterparts. The selections available are the same as
those for the dot-matrix diagram. The single keystroke options
shown in Figure XII-14 are the same as those for the On-Screen
Gantt above except for the last. Pressing a 1,2, or 3 causes the
screen to advance 1, 2, or 3 tasks.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
