How to use PCStat's menus and other features

PCstat uses an menu interface similar to Lotus 1-2-3 (tm) but
enhanced. Menu selections may be made two different ways:
(1) Positioning to them with your arrow keys and either
pressing " Enter " or " Pulling-down ".
(2) Entering the first character of your choice.

The " Esc " key cancels a selection with the exception of
certain operations in which the bottom line will instruct you to
press " Ctrl Break " to abort if desired. To return to the Main
menu press " F10 " or if it is more convenient press " Alt M ".

When entering initialization items or data the " F2 " key will
permit editing of an existing entry. The " F1 " key when
allowed accesses the context sensitive help you are viewing.



What is PCStat

PCStat is a descriptive statistical report program providing
basic statistics and histograms for two related data sets.

Statistics for both data sets and their difference include:
QUANTITY MAXIMUM VALUE +3 STD DEVIATION
+2 STD DEVIATION +3 STD DEVIATION AVERAGE
STD DEVIATION VARIATION RANGE
-1 STD DEVIATION -2 STD DEVIATION -3 STD DEVIATION
MINIMUM VALUE

Histograms provide for 30 bins showing frequency distributions.
The quantities and percent of totals for each bin is also
displayed along with the cumulative percent of totals for both
ascending and descending directions.



Where to use PCStat

PCStat produces an exceptionally easy to comprehend statistical
report for all levels. It is particularly useful to show
comparisons between two related data sets. These might be a
before and after situation, one tool or tester versus another,
one process line versus another, one period versus another, etc.

If you only have one data set to start with you may wish to
prepare a report on that and when you have an additional period
of data keep the old data and prepare a report showing their
comparison. PCStat's Data > Modify > Move feature can be used
to switch data sets or store data in holding areas.

PCStat reports distributed to management and technical personnel
have proven to be a highly effective means of communication.

PCStat data sources

Data for PCStat can come from many sources. Data in Lotus
1-2-3 (tm) compatible worksheets may be combined by directing
the data to a specific data set or holding area. Next you
select a file name and reference a specific range name or range
address in that file. All data from a compatible worksheet also
may be combined to an area starting with data set 1.

ASCII number files may be imported into a specific data set or
data holding area or all the data starting with data set 1. DIF
column files may be also be imported similar to ASCII files.

dBase (tm) compatible delimited files may be also imported. See
Data > Other for instructions. Data also may be manually keyed
in and with Data > View spreadsheet type commands are available.



Initialize: Typing in report titles, format, etc.


Initialize is typically the first step you must select. It
takes you to a screen for defining your report items and puts
you in a range input mode. Type in the requested items changing
positions with the arrow keys. Press " Enter " again when
completed. If you desire titles, periods, notes, etc. may be
left blank but the HISTOGRAM BIN START VALUE and STEP VALUE
along with DECIMAL PLACES and FILE NAME entries are required.

Specific initialization items and recommendations follow.

maximum of 16 characters

FILE NAME: Enter as label a valid DOS filename of from 1 to 8
characters with no extension (extension WKB is
automatically provided for data files)


Note: To enter a number in a non-value item enter a ' first. Page 5

Data: Combine, Import, DIF, Other, Keyin, View, Erase ...


Data is typically the second step you will select. It provides
for getting the data and then if desired viewing and modifying
it. When you select view you will have access to spreadsheet
type commands to make corrections, etc. on your data. When you
select Modify you may copy, move or rearrange your data.

You may also access capability to increase the maximum records
capacity of your PCStat report from the default of 500 to a
maximum of 1000, 2500 or 5000. Memory and disk storage
requirements will increase if you change the maximum.

Specific Data menu choices follow.

COMBINE: Data may be combined from a Lotus 1-2-3 (tm) or
compatible worksheet. When you select menu items
1 through 6 you will be first be prompted for a file
name and then a range name or range cell reference.
That specific range will then be placed in the
specified data or holding area as defined by the menu.

When you select All you will not be prompted for a
file name and the entire worksheet will be combined
starting at Data Set 1. In Data > View you may access
spreadsheet type commands to clean up the data areas.

IMPORT: Data may be imported from an ASCII number file. When
you select menu items 1 through 6 the data imported will
be placed in the specified data or holding area as
defined by the menu.

When you select All the data imported will be placed
starting at Data Set 1. In Data > View you may access
spreadsheet type commands to clean up the data areas.

DIF: Data from a Data Interchange Format column file may be
imported. Selecting different menu items will affect where
data is placed as described in the Import.

OTHER (dBASE): Selecting Other provides a description of two
methods in which data from a prepared dBase (tm)
or compatible database file may be imported into
PCStat. You may wish to use your "Print Screen"
key to keep this for later reference.

KEYIN: If desired you or someone else may manually keyin data.
Select the desired data set or holding area and you will
be put into a range input mode. Type in the data and
press " Enter " again when complete.

Page 6

Data: Combine, Import, DIF, Other, Keyin, View ... (cont)


VIEW: Selecting View first takes you to an instruction screen.
After pressing " Esc " you move to the data area. Once
there you may access spreadsheet type commands to clean
up any data by pressing " F8 ". Press " F10 " to return
to the Main menu. Do not press " F8 " then " F10 ".

ERASE: Data may be erased from any data or holding area or
combination thereof by selecting appropriate item.

MODIFY: Data may be copied or moved from data or holding areas
by selecting appropriate item. Additionally data may be
rearranged to facilitate easier review and clean up.

RECORDS: The maximum records capacity of the standard PCStat
report file is 500. This may be increased to 1000,
2500 or 5000.

Increasing maximum records will require increased
memory and disk storage even if not fully used so you
may wish to keep the maximum records at a minimum
level for the specific report you are generating.

Selecting a lower maximum after selecting a higher
maximum will change records capacity but will not
reduce memory or disk storage unless reloaded.




Calculate: Processing your data


Calculate is typically the third step you will select.


Selecting calculate sends you to a wait screen and proceeds
to calculate all statistical formulas and histograms.


When calculations are complete you are returned to the Main
menu. Typically the next step will be to select the Report
menu.

Report: Print, Options, View, Line, Top


Report is typically the fourth step you will select. In it you
may choose to Print your report immediately or first change
Options such as printer ports or initialization strings. Often
you may wish to select View before printing to check the report.

Specific Report menu choices follow.

PRINT: Prints PCStat report on 8.5 x 11.0 inch paper. LPT1 is
the default interface port but can be swapped to LPT2 in
Options menu. DotMatrix (IBM ProPrinter) initialization
strings are default but can be modified or alternate
strings selected in Options. Graphics is not required.

OPTIONS: Selecting Options provides the following choices.

INTERFACE: Selecting Interface will swap the printer port
from LPT1 to LPT2. Selecting it again will swap
it back to LPT1.

DOTMATRIX: Selecting DotMatrix will take you to a screen
showing initialization strings for an IBM
ProPrinter. These will work on many dot matrix
printers but you are also put into a range input
mode allowing them to be changed as desired. You
must enter a " ||\ " followed by the string.

HPPCL: Selecting HPPCL will take you to a screen showing
HP Printer Command Language initialization strings.
These work on most HP LaserJet and DeskJet printers
or compatibles but you are also put in range input
mode allowing them to be changed as desired. You
must enter a " ||\ " followed by the string.

OTHER: Selecting Other takes you to an additional screen with
no preset initialization strings for input as above.

Note condensed print and 8 lines per inch is required. Once
you choose and accept the codes they will be utilized.

LEFTMARGIN: Selecting LeftMargin will allow changing it.
The default is 8 characters but you may change
it depending on your condensed print size.

RIGHTMARGIN: Selecting RightMargin will allow changing it.
The default is 136 characters and it should
not normally need to be changed.

NUMBERLINES: Selecting NumberLines will allow changing it
however the default of 88 lines is normally
required. Page 8

Report: Print, Options, View, Line, Top (cont)


VIEW: Selecting View first takes you to an instruction screen.
After pressing " Esc " you move to the report area.
Once there you may access spreadsheet type commands to
make any changes desired by pressing " F8 ". Press
" F10 " to return to the Main menu. Do not press " F8 "
then " F10 ".

LINE: Selecting Line causes the printer to step one line.


TOP: Selecting Top causes the printer to advance to the top of
the page.





File: Save, Retrieve, Directory, NewReport, List, Erase ..


File then Save is typically the fifth step you will select.
This will cause your report to be saved in the current directory
with the file name as defined in Initialize and the file
extension WKB.

Specific File menu choices follow.

SAVE: Selecting Save prepares to save the report in the current
directory with the file name as defined in Initialize with
the file extension WKB. Press " Enter " to accept this
or any character to modify directory or file name. If
the file already exists you will prompted to replace.

RETRIEVE: Selecting Retrieve will allow you to retrieve a
different PCStat report. This replaces the one you
have in memory. Available report files in the current
directory will be displayed. Position with arrow
keys and select with " Enter " key. Alternatively
you may enter a file name, use standard DOS wild
cards to limit display or change current directory.

If desired when you load PCStat you may specify a
specific report file by entering the following:

PCSTAT filename
