Laughing Dog Screen Maker READ.ME file:
This file contains any miscellaneous last minute information
that did not make its way into the manual.
----------------------------------------------------------------------------
PRINTING THE DOCUMENTATION FILES:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
All of the Laughing Dog Screen Maker documentation files, having
the extension .DOC, are ready for printing. They are already formatted
using 1" margins and page breaks.
To print a file, use either the DOS copy command:
COPY LDOG.DOC LPT1
or the DOS print spooler, which will allow you to run another
application, while the document is printed in the background:
PRINT LDOG.DOC
Each file is described in the file PACKING.LST. Most files are just
a few pages long, with the exception of the Users Manual (LDOG.DOC), which
is about 100 pages in length.
---------------------------------------------------------------------------
Instant Registration of the Laughing Dog Screen Maker via CompuServe
---------------------------------------------------------------------------
As a convience to those of you that have CompuServe accounts, you may now
register the Laughing Dog Screen Maker instantly via CompuServe's Shareware
Registration Service.
>>>It is not necessary that you download LDOG from CompuServe to use this
service.
>>>Registration Fee will be billed to your CompuServe account.
Here is how you do it:
-- Just log on as usual, then at the ! prompt type "GO SWREG"
-- You will then see the Register Shareware Menu.
-- Choose "Register Shareware" or "Instructions to Register Shareware" for
more information.
-- When you choose the "Register Shareware" option, you will be presented
with another menu allowing you to scan the registration database and
specify the program to register.
-- There are several options: Search for:
Registration ID 344
Title Laughing Dog Screen Maker
File Name LDOG.ZIP
Author's User ID 73650,104
Author's Name Jeff Sloan
Keywords Laughing or Dog or Screen
--When you have located the description of the Laughing Dog Screen Maker,
just follow the directions to register it. The registration fee will be
automatically billed to your CompuServe account, and Yardbird Software
will be notified within 24 hours of your order, which will be shipped
the same or next day!
---------------------------------------------------------------------------
New Features that did not make it into manual:
---------------------------------------------------------------------------
--Added ASCII Text output to the Generate Code/Export Menu. To use it,
select the ASCII Text File option from the Generate Code/Export menu.
You will be presented with another menu which allows you to choose the
line termination method (Carriage Return and Line Feed, or Carriage
Return Only) and change the Last Screen Row included in the file from
the default (whole screen). You then select the "Write Text File" option
to save the file. You will be presented with the standard Save File dialog
box to enter a filename. ASCII Text files are saved with the extension:
"TXT"
NOTE: The following characters are filtered out, as they will not print
out correctly in a text file:
(Hexadecimal values): $07, $08, $09, $0A, $1A, & $1B.
These values will be replaced with spaces ($20).
--Added the ability to automatically insert WildCat! and PCBoard @variables
into a screen. These are only of use to you if you are intending to export
the screen as a PCBoard or WildCat! BBS file. To insert an @variable:
place the cursor at the position where you would like to insert the
@variable string. Press the hot key: <cntl>-V. You will be presented
with a menu allowing you to specify which BBS software you are using
(PCBoard or WildCat!). This setting only needs to be specified the
first time you enter an @variable during the current LDOG session, it will
be set as the default for any subsequent insertions. You may also set
the method of coloring the string from this menu (this setting will also
be remembered for subsequent insertions). The two choices are: 1. Use the
current color, that is, the color selected via the color attribute
selection box. or 2. Use the color at the cursor position. Choose the
method you prefer. NOTE: It is very important that the entire @variable
string be of the same color because if it is not, a color change @code will
be inserted into the middle of the @variable string when written to a file
causing the @variable to become corrupted. Some @variables contain "fill"
characters that are to be filled in by you. The filler character used is
the pound sign "#" Replace the #'s with the appropriate numbers, USING THE
SAME COLOR AS THE REST OF THE @VARIABLE STRING!
--Also note that the last row of screens exported as WildCat! or PCBoard
BBS screens is truncated. This will allow the screens to be displayed
correctly when the background is a color other than black.
---------------------------------------------------------------------------
Changes Made in the Manual
---------------------------------------------------------------------------
--The PostScript output now contains a feature which allows you to easily
specify the number of printouts to produce from a single file. The line:
/#copies 1 def
tells the printer how many copies of the upcomming page to print. Change
the "1" to any other positive integer to print multiple copies.
--The color Pascal code and mono Assembler source code produced by the
Laughing Dog has been changed. The listings in the manual are no longer
correct. They should read:

Command Line Switch added to LDOGSHOW.EXE
---------------------------------------------------------------------------
There is a new command line option (switch) which has been added which may
be useful. It is:
/X exit program with screen intact (don't clear screen)
If a single screen is being displayed, LDOGSHOW will simply terminate,
leaving the screen displayed. It will not require a keystroke, and it will
not clear the screen.
If multiple screens are being displayed via the /L listfile.ext option,
the list will not continually loop, but will instead simply end upon
displaying the last screen in the list. It will not wait for a keystroke
after the last screen, and it will not clear the screen.
---------------------------------------------------------------------------
BONUS PostScript UTILITY ADDED AT LAST MINUTE!
---------------------------------------------------------------------------
The file BLK2EPS.EXE is a utility program which will convert a block file
into an EPS (PostScript) file. The resulting file may be imported into
other programs accepting EPS files just like the full screen EPS files
produced by the Laughing Dog Screen Maker.
USAGE:
BLK2EPS infile.PUP outfile.ext NeedFont?
Where infile.PUP is the full filename of the block file to convert,
outfile.ext is the full filename of the resulting EPS file (recommend
using the EPS extension), and NeedFont? is the digit 0 or 1 (1=include
font information in EPS file, 0=DO NOT include font).
EXAMPLE:
BLK2EPS BLOCK1.PUP BLOCK1.EPS 1
This example will take the file "BLOCK1.PUP" in the current directory
and convert it to an EPS file including the font, and save the new
file as "BLOCK1.EPS" in the current directory.
NOTE: You may also convert a full screen xxxxxxxx.DOG file to EPS using this
utility.
-----------------------------------------------------------------------------
Mind Boggling Example of what can be done with the IBM extended chars!
-----------------------------------------------------------------------------
Check out this file: MAGIC.DOG
I found it originally as ANSI art on a local BBS, and I haven't been
the same since. I didn't know such things were possible! This is just an
example of the fantastic images you can create using the Laughing Dog Screen
Maker (NOTE: MAGIC.DOG was not created with LDOG, it was captured from the
original ANSI using LDOGRAB.EXE)
