- INTRODUCTION to TDXL -
TDXL is a TSR (Terminate and Stay Resident) program that facilitates
the creation of PCBoard @X format color text screens. TDXL allows
PCBoard BBS Sysops and Screen Designers to use TheDraw(TM) to create
Newsfiles, Bulletins and Welcome color text screens.
Pressing Ctrl-T activates TDXL, while in TheDraw, and allows you to
View, Load and Save PCBoard @X formats directly. This eliminates the
need to create ANSI.SYS color text screens and then convert them.
Note: TheDraw(TM) is a well supported "shareware" color text screen
drawing program, available on many Bulletin Boards. TheDraw
has many useful features for the creating screens. It is
recommended that you use TheDraw version 3.3 or later with
TDXL.
TheDraw(TM) is Copyright by Ian E. Davis and TheSoft Programming
Services. Fred Bertagnolli is not an associate of Ian E. Davis.
Please support the "shareware" policies of TheDraw.
---------- IMPORTANT NOTICE TO ALL USERS OF TDXL ----------
IMPORTANT: TDXL will only work if TheDraw program name is unchanged.
*** DO NOT RENAME THEDRAW.EXE to another .EXE name. ***

- Overview of TDXL Features -
o TDXL was designed to replace CONVERT, EXLIST, and PCBdraw
when used with TheDraw. Most PCBoard Sysops are familiar with
these programs, and their limitations and drawbacks.
o Your screen designs will display and scroll correctly when saved by
TDXL, without color wrap around problems, and are compressed to
a minimum file size.
o TDXL can grab color text screens while you are ON-LINE, and saves
the screen in compressed PCBoard @X format.
o TDXL can be used with or without TheDraw. For example, you can TYPE
an ANSI.SYS color screen, and save it to @X format.
o You can view PCBoard @X files anytime, even from a running program.
o Use of TDXL eliminates the need for duplicate ANSI files of your
PCBoard screens.
o Using TDXL with TheDraw is a better drawing environment than other
systems that write @X commands directly. A few reasons are:
TheDraw supports a mouse, multiple pages, and can import many text
file formats. Screen designing is EASY with TheDraw.
o TDXL supports loading @X screens or text files longer than 25 lines
and can load @X files to TheDraw pages.
o TDXL allows you to scroll through long text files or PCBoard format
files. You can insert just the Page you want directly into TheDraw
for further colorization/editing.
o TDXL is extremely easy to use. It allows saving of 1 to 25 screen
lines, allows adding an @CLS@, and automatically compresses the
@X file to a minimum size. You also have control over the last
CR-LF in the file.
o TDXL is written in 'C' by a professional programmer with 10 years
programming experience. TDXL output has been heavily tested using
two different PCBoard BBS systems with no problems.
o Registered Users of TDXL will receive a password which enables
additional features built into TDXL, including the ability to
mirror (flip) horizontally and vertically and to view screens in
black and white mode. Registration will also remove the "SHAREWARE"
reminder that appears on line 24 of the non-registered version. We
do not apologize for this minor annoyance. It is intentional.
Note that the reminder DOES overwrite part of line 24, and appears
each time you Load a file.

- 7 -
- Installation of TDXL -
TDXL is a TSR. Always load this program from the DOS command line
before running any other programs. Never load any TSR while in a
DOS SHELL.
Note: TSRs sometimes conflict with each other; therefore, it is
recommended that you do not have other TSR programs in memory
while running TDXL. If you do have multiple TSRs and experience
problems, then try loading the TSRs in a different order.
All TDXL DOS command lines assume you are in the Directory where
TDXL.EXE is located. We recommend installation of TDXL.EXE on your
hard disk. TDXL.HLP must be in the same Directory as TDXL.EXE.
* TO LOAD TDXL TSR... at the DOS Command Line prompt type:
TDXL
TDXL now installed!
Press CTRL-T to activate the TSR
------------------------------
* TO REMOVE TDXL from MEMORY... at the DOS Command Line prompt type:
TDXL QUIT
TDXL now removed!
------------------------------
* ACTIVATING the TDXL TSR...
Press CTRL-T (the hot key) while running THEDRAW.EXE. A TDXL main
menu window pops-up and is ready to View, Load or Save @X files.
------------------------------
* SPECIAL TDXL Command Lines...
Special commands that some users may wish to use if the CTRL-T
hot key conflicts with other program controls (normally not used):
TDXL wait Puts TDXL on temporary hold, if it is already in memory.
This deactivates the CTRL-T hot key.
TDXL restart Restarts TDXL if it was on hold, and reactivates the
CTRL-T hot key.
TDXL uses about 28K of memory when loaded. We recommend that you
use the TDXL QUIT command line to remove TDXL from memory when you
have finished. This will make the 28K of main memory available to
other programs.

| PCBoard @X Screens |
--Copyright 1991 F. Bertagnolli--
The 4 options are for View, Load, Save a PCBoard @X file and Toys.
Press: V, L, S, T to access menu options.
T)oys option is available to registered users only and allows
the current screen to be mirrored horizontally or vertically.
Press: Esc to exit TDXL and return to TheDraw.
Press: F1 to see the single help screen. TDXL.HLP (the Help file)
must be in the same Directory as TDXL.EXE.
- 9 -
V)iew: View a PCB @X file or a text file, then restore previous
screen.
-------------[ View ]------------
| Filename to View: |
|[_____________________________]|
| |
| Display in Color : Y/N [ ] |
| Reg. option |
| |
| |
| |
----------------- [Esc]:Cancel --
o Filename to View: May have a Directory Path included with the
filename; i.e., D:\DIR\PCBFILE.PIC
o You may press Esc at any time to cancel the field edit and
return to the Main Menu.
o If the 1st character of an existing file does not begin with @,
you are prompted: @ NOT FOUND! Proceed: Y/N [N].
TDXL assumes that PCBoard @X files always begin with @. "Proceed"
is used to remind you the filename you entered is probably
not a PCBoard @X format file. However, you may proceed with a Y
response and view ASCII text files.
Files longer than 25 lines are prompted:
[ More: Any Key or Esc ]
at the bottom of the screen. Pressing Any Key will scroll through
file, line by line. Pressing Esc will show how many lines were in
that file, and waits for an additional Esc key press.
o Note that TDXL does not support ANSI.SYS control codes. Use TheDraw
to load in an existing .ANS file. Then use TDXL to convert them to
PCBoard @X format. Or from the DOS command line, TYPE FILE.ANS and
save the screen to @X format with TDXL.
o Display in Color? Y/N: [N] is available only to registered owners.
This option is useful for viewing a PCBoard @X format file, in
black and white, and provides a means of seeing what the on-line
screen will look like if a user has color turned off. We recommend
you check your screens in black and white mode, to be sure they
display as you intended.
- 10 -
L)oad: Loads a PCB @X file starting at (1,1). If TheDraw(tm) is running,
prompts for PAGE #. Draws to the video page and copies to TheDraw
page buffer. The current TheDraw Page should match PAGE # selected.
-------------[ Load ]------------
| Filename to Load: |
|[_____________________________]|
| |
| TheDraw PAGE : 1-8 [ ] |
| |
| Page # is the active page |
| of TheDraw, when running. |
| |
----------------- [Esc]:Cancel --
o Filename to Load: May have a Directory Path included with the
filename; i.e., D:\DIR\PCBFILE.PIC
o You may press Esc at any time to cancel the field edit and
return to the Main Menu.
o If the 1st character of an existing file does not begin with @,
you are prompted: @ NOT FOUND! Proceed: Y/N [N].
TDXL assumes that PCBoard @X files always begin with @. "Proceed"
is used to remind you the filename you entered, is probably not
a PCBoard @X format file. However, you may proceed with a Y
response and LOAD ASCII text files of any size.
o TheDraw Page: 1-8 is accessed only if you are currently running TDXL
within TheDraw. The default page is 1. You
should first be on the specified TheDraw Page
before loading to it.
For example: If you are on Page 1 and tell TDXL to load to Page 8, the
current Page 1 screen will be temporarily overwritten.
This happens because TDXL has no way of knowing what Page #
you are currently displaying with TheDraw. TDXL will load
TheDraw Page 8 with the file, but Page 1 will not contain
current screen data. To refresh TheDraw screen, after
exiting TDXL, use TheDraw command ALT-E PAGE# to redraw/or
move to the desired Page #.
o Files longer than 25 lines are prompted with:
[ More: Any Key or Esc ]
at the bottom of the screen. Pressing Any Key will scroll through
the file, line by line. Pressing Esc will Load the current screen
into TheDraw, and will show you the number of lines in that file.
Pressing Esc again, exits TDXL and returns you to TheDraw.
Lines longer than 80 characters are truncated.
- 11 -
Load: continued
o After a Load, when running TDXL and TheDraw, TDXL moves the cursor
to position (1,1). Line 24 of the non-registered version is
overwritten by intentional "Shareware" reminder. If you have
not registered TDXL, please do not complain about this annoyance.
o By the way, the scrolling Load feature of TDXL is something TheDraw
cannot normally do with ASCII files.
o These PCBoard @Commands@ are ignored during View/Load, since they
are not displayed on-line and they do not expand any system information:
@CLS@, @POFF@, @QOFF@, @PON@, @QON@, @MORE@, @PAUSE@ and @AUTOMORE@.
All other @Commands@ may be included in a screen design: i.e., @USER@,
and will be Loaded with TDXL. Except for @CLS@, SysOps should add
these non-expanding @'s to a saved file, manually. Or put them on the
first line of the screen design, followed by an @CLS@ command.
o Note to Non-Sysops: Most sysops do not like users to use any of the
color code commands in uploaded messages. Please abide by local Sysop
customs, and do not use TDXL to create screens which are not Sysop
approved. It is also worth mentioning, that @X color codes are not
recognized by many off-line mail reader programs, including SLMR 2.0.
-------------------------------------------
S)ave: Saves the current screen to PCB @X format. Prompts for number of
Rows to Save. Allows adding an @CLS@. Allows control over a CR/LF
at the end of the Saved file. Save always starts at position (1,1).
-------------[ Save ]------------
| |
| Ending Row : 1-25 [23] |
| Insert CLS : Y/N [N] |
| Insert CR/LF : Y/N [Y] |
| |
| Filename to Save: |
|[_____________________________]|
| |
----------------- [Esc]:Cancel --
o Ending Row: 1-25 Enter the last Row Number (screen line) you wish
to save. A column of Row numbers appears temporarily
on the Left side of the screen, showing the current
row number in Red.
o Insert CLS If Y is selected, @CLS@ will be inserted at the
first position in the Saved file.
o Insert CR/LF If N is selected, the last line in the file will
not have a Carriage Return / Line Feed combination.
This is useful for displaying a full 23 lines when
on-line, without scrolling off the screen.
- 12 -
Save: continued
o Filename to Save: may have a Directory Path included with the
filename; i.e., D:\DIR\PCBFILE.PIC
o You may press Esc at any time to cancel any field edits and
return to the Main Menu.
o It is a good idea to View a saved file to make sure you have
exactly what you intended to save. Registered users should also
View the file with No Color, to make sure the file displays as
intended, in Black and White mode.
o If a filename already exists, Save will prompt:
Overwrite filename? Y/N/A:[N] A option is new, starting with
TDXL release 1.c
Entering Y Overwrites the file.
Entering A Appends to an existing file. Useful
for creating multiple page bulletins files.
Entering N Aborts the save process.
------------------------------------------------------------------
T)oys: This option is available only to registered users. Pressing
T from the main menu prompts for the current TheDraw Page #,
if TheDraw is currently active.
Press H or V to mirror the current screen. Press Esc to
return to the main menu. This option is useful for making
symmetrical screen designs. Example: Copy Page 1 to Page 2
with Thedraw, then Flip page 2. Copy the desired block of
the mirrored screen from Page 2 to Page 1 with Thedraw.
TheDraw Page # should be the same as the your current
TheDraw Page being displayed. The option is not prompted
if TheDraw is not currently running.
-------------[ Toys ]------------
| |
| TheDraw PAGE : 1-8 [___] |
| |
| |
| Flip: H)orz V)ert |
| |
| |
| |
----------------- [Esc]:Exit ----
Note that TDXL does not attempt to "fix or flip" box corners
or other specialized characters, when the screen is flipped.
The flip options are intended to be a drawing aid/tool.
- 13 -
- If you have problems running TDXL and TheDraw -
o Do Not RENAME THEDRAW.EXE to some other name. TDXL will only work
if THEDRAW.EXE filename is used to load and run TheDraw.
o TDXL was designed for use with TheDraw versions: 3.3, 4.1, 4.3, and 5.0
TDXL may not work with older versions of TheDraw, since they have
not been tested.
o TheDraw SETUP: TDXL works correctly with TheDraw when the default
page size of 80 x 25 is the current setup. Other
TheDraw page sizes will scramble TDXL @X file Loads.
- Using TDXL as a stand alone program -
TDXL can work outside of TheDraw to capture the current screen while
other programs are running.
For example: ECHO OFF
TYPE SCREEN.ANS (with ANSI.SYS color control codes)
Press CTRL-T and SAVE the current screen with TDXL.
For example: While ON-LINE, press CTRL-T and SAVE the screen being
viewed with TDXL, for later editing.
Note: TDXL may work with other screen drawing programs or editors, if
they use the video screen memory for screen storage buffers.
Use TDXL with other programs at your own risk.
- 14 -
- A Help List for PCBoard Screen Designers -
1. Limit the maximum size of your screens to 79 columns x 23 rows.
TDXL supports a maximum page size of 80 x 25. You are advised to limit
screen designs to 79 x 23, to allow for various communication programs.
Testing has shown some communication programs do not display 80 wide
screens correctly. Using a maximum width of 79 characters seems to
correct this problem. (column 80 is blank)
2. ASCII codes below 32 (decimal) may not display, or may have side
effects, if included in screen designs. Use low ASCII codes with
caution, and test the resulting file on-line. Example: ProComm
displays ASCII code 16, while Qmodem does not.
3. Color 0,0 (Black on Black code X00) saves the last color. TDXL
sets this color code, to Light Gray on Black, during View or Load.
A future release may support X00 save and XFF restore sequences.
4. If you are not a Sysop, do not create color PCBoard BBS messages,
without prior Sysop approval. Messages with @X codes are not
supported by most offline mail readers.
5. TDXL allows removal of the last CR/LF in the saved file. This option
is available because PCBoard System Prompts begin with a CR/LF.
Assuming you have also included @CLS@ in a saved @X file and have
removed the CR/LF from a screen with 22 lines, the next PCBoard
System Prompt will be on line 23, when displayed ON-LINE.
6. A program called CONVERT.EXE (converts from ANSI to @X format)
incorrectly interprets low ASCII codes (31 or less) and can cause
undesired screen color wrap around.
Advice: Use TDXL with TheDraw to include low ASCII codes and to
correctly convert and compress @X files.
7. Those who have used a program called PCBdraw are advised this
partial clone of TheDraw, does not support a mouse and the
non-registered version does not support multiple pages. PCBdraw
cannot read ANSI.SYS files or other formats supported by TheDraw.
Compression routines used by PCBdraw, attempt to minimize the
@X file size, and in doing so, ignore the possibility of color wrap-
around. This flaw appears when PCBoard sends a file created by
PCBdraw, and the color screen scrolls or is longer than 23 lines,
when received by a user's communication program.
TDXL fixes this problem by always ending a line with the default
DOS color of Light Gray on Black, while still compressing the @X
files to a minimum size.
Advice: Use TDXL with TheDraw to get screens that don't color wrap.
8. TDXL allows specifying the number of rows to Save from 1-25, a
feature lacking in PCBdraw. One- or two-line custom prompts
might be created by a Sysop, if PCBoard allows them. Or you might
wish to create short screens, for faster ON-LINE displays.
- 15 -
Help List: continued
9. Consistent use of TDXL with TheDraw will eliminate the need to
have backup ANSI.SYS files of your screen designs. And @X files
are likely to be smaller in size, than an equivalent ANSI.SYS
file.
10. Those who have used a program called EXLIST: TDXL imports @X files
directly to TheDraw. Imported files can then be save in ANSI format
or many other formats, if desired.
Advice: Use TDXL with TheDraw to import @X and save to ANSI.
11. PCBoard @X files do not support ANSI.SYS ESC GOTO sequences;
therefore, screens designed for PCBoard systems cannot display
TheDraw Animation type files in @X formats.
12. To create multiple page Newsletters and other long @X displays:
Easy Method: Use an existing filename when Saving and Press A
to APPEND the current screen to the existing file.
Or : SAVE EACH PAGE with TDXL. Then concatenate the files
with the DOS COPY command:
COPY PAGE1 + PAGE2 + PAGE3 + ...
You can scroll through and verify the long file, with TDXL, after
joining individual pages together, using the View option.
13. For faster and smaller PCBoard BBS ON-LINE screens, create designs
containing mostly blank spaces. Screen designs have blank spaces
on the RIGHT SIDE of the screen will display faster than screens
surrounded with a box design.
TDXL's compression scheme does not include blank spaces on the RIGHT
SIDE of the screen in the Saved file, if the spaces are drawn on a
BLACK background.
14. If you need to have a series of non-expanding PCBoard @Commands@
in the file, consider putting them in the first line of the
file; i.e., @QOFF@@CLS@ works nicely. TDXL will ignore these
"invisible codes" when you Load a file containing them. However,
they can be placed in a Saved file, by typing them in TheDraw before
you Save the file. Test all files containing @COMMANDS@, on-line.
15. If PCBoard users complain about not seeing the last part of the
LOG OFF screen, consider putting in @PAUSE@ in the last line
of the PCBoard @X file. That way, they can press a key to
continue or they will automatically be logged off in 10 seconds.
They will see the whole LOG OFF screen, without truncation.
16. Add variety to your system by rotating Welcome screens.
Ask your users to create Welcome screens.
- 16 -
- Sample PCBoard @X screens -
The TDXL-PCB.ZIP file should contain several sample screens.
Permission is granted to change or use these screens if you
wish to use them on your system. One of these files is an
example of a PCBoard @X screen containing more than 25 lines.

Many ideas incorporated into TDXL were included at Glenda's suggestion.
Glenda gets all the credit for debugging, testing, and putting up with
a sometimes cranky programmer. The sample PCBoard screens include
examples of Glenda's PCBoard screen designs. Glenda has designed
hundreds of PCBoard Welcome screens and now uses TDXL because it
makes previous methods obsolete.
