VTL 2.0 - Video Tape Library Dec. 1989 - by Paul E. Castle II

*B 1,General Help


VTL 2.0 - Video Tape Library

VTL was written by Paul E. Castle II

Syntax: VTL [-switches]

-b = BIOS screen writing
-c = CGA snow elimination
-h = Display VTL syntax
-i = Introductory screen inactive
-m = Monochrome attributes forced
-p = Path to VTL files
-x = Exploding windows active

*P

VTL is a menu driven, video tape tracking system. It
is written in Turbo C v2.0 and uses Mike Smedley's
extended C library CXL v5.0.
VTL is started using the above ^SYNTAX^. From that
point on, you simply make menu selections and enter
data.
Some of VTL's features are controled by keyboard
key combinations and function ^KEYS^. These keys
provide scrolling, screen print, processing, help, and
many other functions.
All data entry screens recognize a wide range of
^EDIT KEYS^ that make data entry quick and easy.
At all times, HELP is just a keystroke away. Just
press "F1" and a help window will pop up.

*P

If you have any questions, comments, complaints, or
suggestions, I can be reached through:

*B 2,Syntax

VTL - Video Tape Library

Syntax: VTL [-switches]

-b = BIOS screen writing
-c = CGA snow elimination
-h = Display VTL syntax
-i = Introductory screen inactive
-m = Monochrome attributes forced
-p = Path to VTL files
-x = Exploding windows active

At start-up, VTL can be configured through the use of
command line switches.

*P

If you wish to run VTL from a remote terminal, the
"-b" switch will force VTL to use BIOS calls for I/O.
Without this switch, I/O is performed directly to the
video memory.
The "-c" switch can be used if you experience "snow"
during VTL direct memory I/O. This switch activates
VTL snow removal.
The "-i" switch, not covered in the VTL documentation,
prevents the introductory screen from being displayed.
VTL defaults to color output. You can force VTL to
use monochrome attributes by using the "-m" switch.
Using the "-x" switch starts VTL with exploding windows
active. Once inside VTL, you can toggle exploding
windows OFF and ON using the [F10] key.

*P

VTL can be run from any directory. However, if VTL
is run from a directory other than the one that holds
its files, you must use the "-p" switch to indicate
the location of its files.
If you do not run VTL in the same directory with its
files and you do not want to use the "-p" switch, you
can use the environment variable "VTL". Just use the
DOS SET command to set VTL equal to the path to your
files. For example:

SET VTL=C:\VTL

Switches can be run togeather (ie: VTL -mbx) or used
singly (ie: VTL -m -b -x). Either the "-" or "/" can

*P



be used as the "switch character". If switches are run
togeather, the "-p" switch MUST be the last in the list.

*B 3,Keys

Key Combinations and Function Keys

Certain key combinations and function keys perform
specific functions within VTL, as mentioned under the
^General Help^.
At any time, you can activate a HELP screen, specific
to where you are, by pressing [F1].
The [Esc] key allows you to exit the screen/function
you are currently in. Pressing [Esc] at the Main Menu
will exit VTL. Using the [Esc] key to exit VTL does
NOT cause a problem. VTL will go through its normal
exit routine and all updates and deletes will be applied.
You can, also, use the [Alt-X] key combination to exit
VTL from anywhere. You will be asked to confirm that

*P

you wish to exit VTL. If you respond "Y", all updates
and deletes will be applied and the session will end.
If you reply "N", you will be left at the same point
that you pressed [Alt-X].
The [F2] function key is used to complete processing.
This is true in the Search Criteria, Add, Update, and
Delete windows. When Updating or Deleting records, you
will be prompted to confirm the requested action prior
to the record being processed. When selecting search
criteria, [Ctrl-Enter] or [Enter] while in the last field
will start the search process.
Pressing the [F6] function key will dump the current
screen contents to the printer. Be sure the printer is
on and ready. I do not trap this error.

*P

[F10] can be used to toggle "exploding windows", as
mentioned in the ^Syntax^ help. Exploding windows are
a nice visual effect that can eventually drive you to
insanity. One note, a window will close in the same
manner it was opened no matter what the toggle at the
time.
Finally, the [PgUp] and [PgDn] keys are used to
scroll through multiple screens of information.

*B 5,Update Master File

**** UPDATE MASTER FILE ****

The UPDATE function allows you to modify the master
file. This includes the initial entry of master file
records, deletion of unwanted or unneeded records,
updating of individual master records, and a search
feature that allows you to specify search criteria and
then page through matching entries.

*B 6,ADD



**** ADD ****

The ADD feature is used to make the initial entry of
master file records. After selecting ADD, you will be
presented with the VTL input screen. Fill in the data
fields and press [F2] to process the screen and add
the record to the master file.

See also: ^GENERAL HELP^ ^UPDATE MASTER FILE^

Press [Esc] to exit HELP
*E

*B 7,UPDATE

**** UPDATE ****

The update feature is used to make changes to existing
master file records. After selecting UPDATE, you will
be presented with the VTL search criteria screen. Enter
one or more of the key values, press [F2], and the
master file will be searched for matching entries. If
matching entries are found, you will then be given a
screen, like the one used to ADD records, with the data
from the matching master records displayed. You can
page through these records, make changes, and use the
[F2] key to update the record. Changes to the master
record take effect immediately. If an index field is
*P

modified, the associated index file record will not be
updated until the VTL session is ended. This can
produce some strange results during the current session.
For example, you add PSYCHO with John Wayne as a star.
You realize your mistake, enter UPDATE and change John
Wayne to Anthony Perkins. If you search on Anthony
Perkins, now, PSYCHO will not match. The index file
still indicates John Wayne as the star. Update index
fields with care!

*B 8,DELETE

**** DELETE ****

The delete feature is used to remove master file
records. After selecting DELETE, you will be presented
with the VTL search criteria screen. Enter one or more
of the key values, press [F2], and the master file will
be searched for matching entries. If matching entries
are found, you will then be given a screen, like the
one used to ADD records, with data from the matching
master records displayed. You can page through these
records, locate the one(s) you wish to delete, and press
the [F2] key to delete the record. Unlike the Update
feature, which updates immediately, deleted records are
not removed until the end of the current VTL session.
*P

At that time, the deleted records are removed and the
index files updated. If you delete a record and then
decide you made a mistake, simply select UPDATE, retrieve
the mistakenly deleted record, and use [F2] to process.
This will reset the delete flag and "re-add" the record.

Writer, Producer, Male Lead (three entries), and Female
Lead (three entries). Once search has been selected,
you are presented with a search criteria screen. You
may enter one or more of these fields and then press
[F2] to process. The master file is then searched
for matching records and the data is displayed on a
screen like the data entry screen. You may then page
through the entries using the [PgUp] and [PgDn] ^Keys^.
*P


This feature exists as a Main Menu selection, an
UPDATE MASTER FILE selection, and as a part of the
Update and Delete features.

  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/
