Just What In The Heck Is BATMAN Anyhow:
BATMAN is a comic book character that achieved zenith popularity
during the run of a network television show of the same name
which aired during the 1960's.
But that's irrelevant. This program, BATMAN, is a tool for
bringing a little life an pizazz to your MS-DOS batch files. The
program allows you to do a number of tricks which are either
1) impossible to with conventual MS-DOS commands
2) require cryptic ASNI code to produce or
3) would otherwise require a bunch of separate utilities
I'll get into more detail in a moment. For now we can say that
BATMAN will allow you to;
* Make the speaker beep for any number of times, at any tone
and with any duration of tone and gap between the tones
* Play 'canned' songs and interesting sound effects
* Switch to any video mode (this saves floppy disc users
from having to have the MODE program on every disc).
Support is included for 43 lines on EGA systems and 50
lines on VGAs.
* Get responses from users and thus allows the batch file to
react to their answers
* Set foreground and background colors for text
* Write text at any position on the screen
* Solicit "Yes or no" response with many variations.
* Draw boxes with border for putting detail text into
* And many other stunts

NEW AND IMPROVED:
I have made a number of improvement since 1.0. Briefly they are;
1) The YORN command doesn't make a mess of the screen any more.
Originally it produced an error message which, if the user made
too many mistakes, would cause the screen to scroll away. Now an
error window opens, tells the user to try a "yes or no" type
answer, and then disappears with the first keystroke. I have used
a set text attribute for the error box (red background, black
foreground), which may interfere with your choice. Later I'll
write in a test of colors and change them dynamically.
2) New commands which clear the screen (an oversight in the first
version), draw a box and report the current video mode.
3) New sound effects/songs up to five from three (there should be
more, but I've been busy).
4) Process BATMAN commands from a file for faster response.
Sound good? Well flip the page and I'll start describing the
program.

How Do You Use BATMAN:
Well, first you use the Bat Telephone, dial 1-800-BAT-CAVE . . .
I'm sorry about these silly outburst, but this is a silly day.
Besides, the name of the program makes for obvious jokes.
To run BATMAN, simply type BATMAN followed by one of the
supported parameters. Since BATMAN is designed for use in batch
files, you will probably want to experiment by building your own.
In this package, there is a batch file named DEMO.BAT which shows
off some of the features of BATMAN.
Each of the parameters is a command name which can be abbreviated
to three letters (it was four in version 1.0, but I found a good reason
to decrease the character count). For example, the following two
commands function identically;
BATMAN VIDEOMODE(CO80)
BATMAN VIDE(CO80)
You can use more than three letters if you like. The only
restriction is that the first four characters must match a
command name exactly. You could say;
BATMAN VIDEO_MODE_HAS_POWER(CO80)
without making the program bomb. As you may note, the VIDEO
command has a parameter all its own, which is encased in
parenthesis. Most commands have such a parameters, some have
several, and a few have none at all. Don't let this bother you.
If you ever forget how to structure a parameter, just type in
BATMAN with no commands (or with the HELP command) and a short
list of commands and parameters will be displayed.
You can combine commands on a single line. This is advised since
each command line that calls BATMAN causes the computer to hunt
down the program, allocate memory, load and initialize the
program, and more time consuming processes. This new version also
allows you to use an entire file of BATMAN commands which makes the
process even faster. The only time you need to exit BATMAN is when a
batch file decision is required (i.e. the IF statement).
Finally, I suggest you keep BATMAN in the first directory in your
path statement (this section really only applies to hard disc
users, so floppy folks can read on). My \UTIL directory is first
in the path list and I keep BATMAN at the top of the directory
(there are a number of utilities that allow you to shuffle the
order in which files appear in a subdirectory). This speeds up
batch file execution greatly and saves some wear and tear on the
drive.

Some much for the basics. Flip the page and we'll learn about
each of the parameters.
BEEP(num,dur,frq,gap)
This command produces beeps of a specific tone, duration and
delay (i.e. no sound at all) between beeps.
num: The number of beeps you want to hear.
dur: The length of the beep in milliseconds.
frq: The frequency, or tone of the beep.
gap: The delay between beeps.
Use numbers only. Using character will produce an error message
(try it, you'll be surprised). You can use negative numbers, but
the program ignores the negative value, and uses the absolute
value. The commas are the only delimiters allowed in BATMAN. The
command;
BATMAN BEEP(3,500,440,250)
produces three beeps. Each beep is 1/2 second long and is played
at 440 Hz (or middle A). Silence is heard for 1/4 second between
each beep.
I decided to leave the parameters as numbers instead of devising
some coding scheme. This saves program size and processing speed
and makes BATMAN run faster. Since BATMAN may be used many times,
it is essential to keep it as tight as possible.
For the convenience of those with a musical background, the
following chart shows the best approximate value for frq to use;
OCTAVE NOTE NUMBER │ OCTAVE NOTE NUMBER
══════════════════════════════│══════════════════════════════
0 A 27 │ 4 F 349
0 B 31 │ 4 G 392
1 C 33 │ 4 A 440
1 D 37 │ 4 B 494
1 E 41 │ 5 C 523
1 F 44 │ 5 D 587
1 G 49 │ 5 E 659
1 A 55 │ 5 F 698
1 B 62 │ 5 G 784
2 C 65 │ 5 A 880
2 D 73 │ 5 B 988
6
2 E 82 │ 6 C 1046
2 F 87 │ 6 D 1175
2 G 98 │ 6 E 1318
2 A 110 │ 6 F 1397
2 B 123 │ 6 G 1568
3 C 131 │ 6 A 1760
3 D 147 │ 6 B 1975
3 E 165 │ 7 C 2093
3 F 175 │ 7 D 2349
3 G 196 │ 7 E 2637
3 A 220 │ 7 F 2794
3 B 247 │ 7 G 3136
4 C (mid) 262 │ 7 A 3520
4 D 294 │ 7 B 3951
4 E 329 │ 8 C 4186
I'll update this chart in future release to show the values for
sharps and flats. For now, your best bet is to pick a number
between the two surrounding values (i.e. 1st octave A# should be
about 58).
As I noted before, these are the closet approximate value for the
frequencies possible. They are close enough that the untrained
ear won't notice the difference. For duration and gap, I offer
the following;
VALUE │ BEAT
═════════│═══════════════════════
1000 │ Hole note
500 │ Half note
250 │ Quarter note
125 │ Eighth note
66 │ Sixteenth note
31 │ Thirty second note
PAUSE(sec)
Causes the batch file to do nothing. This is important. It allows
users to read messages, or admire your beautiful display.
sec: Time to delay in seconds. This measure is approximate
(i.e. it is not exactly a second, but a touch more).
VIDEO(mode)
Changes the display mode used by your video adapters. Since MS-
DOS can support both a color and monochrome monitor in a single
computer, this command is handy for adjusting this value (you can
also use the MODE program supplied on your MS-DOS disc, but
that's just one more file to keep track of). Additionally, you
7
can adjust the line densities of EGA and VGA monitors.
mode: Text which describes what video mode to use. The
following list contains the only valid parameters;
CO80: Set video for a color adapter and 80 characters
across the screen.
BW80: Same as above, but in Black and White.
CO40: 40 column video in color.
BW40: 40 column video in Black and White.
MONO: Switches to a monochrome adapter.
EGA43: Switches an EGA system to 43 lines of text and 80
columns.
VGA50: Switches a VGA system to 50 lines of text and 80
columns.
Don't worry too much about choosing the wrong parameter. MS-DOS
is forgiving on this point and won't let you do the impossible
(like switch to MONO if you do not have a monochrome adapter
installed).
MODE
Reports what mode the CRT is in. This is very handy if you try to create
a batch file set which works differently with any monitor/card
combination (if you do this, you are a prime masochists).
The values reported by MODE are returned in the errorlevel DOS variable,
and can have the following values;
0: Black and white in 40 column mode
1: Color in 40 column mode
2: Black and white in 80 column mode
3: Color in 80 column mode
7: Monochrome monitor, 80 columns
SONG(num)
Plays a tune or sound effect already stored in BATMAN (I am
working on the theme song from the old Batman program). At
present, there are only three tunes stored.
num: A number from 1 to 4.
1 - A rising pitch which lasts for a few seconds
2 - A laser blast
8
3 - A short tune akin to "Irish Eyes"
4 - A butchery of the interlude in Jethro Tulls
"Mother England Reverie"
5 - A note quite right version of the "Close Encounters"
contact tune
I have a goal of adding one more tune for every new feature added
to BATMAN. In time, I suspect the tune will exceed 15 or 20. If
you want something else, try experimenting with the BEEP command
and put as many BEEPs on a command line as possible.
ERRORCODE
This command takes a number from the user and uses it as the exit
code. This code, MS-DOS environment variable ERRORLEVEL, can then
be used to branch elsewhere in the batch file. There is no
parameter for this command.
The best use for ERRORCODE would be in constructing a menu. Here
is an example batch file of a simple menu system;
BATMAN WRITE( 1 ........ Lotus 1-2-3)
BATMAN WRITE( 2 ........ Space Invaders)
BATMAN WRITE( 3 ........ PC Paintbrush)
BATMAN WRITE( Enter a number:) ERRORCODE
IF ERRORLEVEL 1 GOTO LOTUS
IF ERRORLEVEL 2 GOTO INVADERS
IF ERRORLEVEL 3 GOTO PAINT
...
Actually, there is another step involved, but this shows the
intent. Be careful not to use ERRORCODE and YORN commands on the
same BATMAN line. Both set ERRORLEVEL and using both will cause
the first to be unusable.
INFO
Displays information about BATMAN, myself and where to send money
and bug reports.
FOREGROUND(fcolor,BLINK)
Sets the foreground text color. All text sent to the screen after
this command is processed will be displayed using the color
specified. An optional parameter, BLINK, will cause the
characters to blink on and off while they are on the screen.
9
fcolor: One of 16 foreground colors. They are;
BLUE LIGHTBLUE
GREEN LIGHTGREEN
CYAN LIGHTCYAN
RED LIGHTRED
MAGENTA LIGHTMAGENTA
DARKGRAY LIGHTGRAY
BROWN YELLOW
BLINK: If blinking characters are desired, use the key word
BLINK. No other value will do.
Use the names exactly as they appear in this chart. It doesn't
matter if they are upper case, lower case or mixed. Just don't
separate the word roots.
BACKGROUND(bcolor)
Sets the background color, the color behind the actual characters
to be printed.
bcolor: Only eight colors are available for the background;
BLACK BLUE
GREEN CYAN
RED MAGENTA
BROWN LIGHTGRAY
Please note that if you select BLACK as your foreground color,
you better select a new background color, and one other than
black. Otherwise, all your text will simply never show up.
HELP
Displays a short help screen, the same as if you ran BATMAN
without any commands. There are no parameters for this command.
WRITE(text)
Displays text on the video screen. Text is limited only to the
length of the command line in your batch file and one character.
text: The text you want displayed. DO NOT USE PARENTHESIS
AS PART OF YOUR TEXT!!!!! There is a technical
reason why you can not use a right paren ")" in this
command (for the technically minded, read TECHNICAL
10
ISSUES at the end of this document).
The text will be drawn at the current cursor location. The cursor
will remain at the end of the text line. This allows you to use
commands ERRORCODE and YORN to get responses from users, and have
the responses displayed at the correct position on the screen
(not on the next line or some silliness like that).
GOTO(x,y)
Causes the video cursor to move to the defined row and column.
This is very handy for making dazzling displays with banners,
marked fields and the like.
x: The column you want to start in. Normally a position 1
through 80, except when your are in 40 column mode.
y: The row to move to, anywhere from 1 to 50 depending on
video adapters and mode settings. Normally 1 through 25.
Use numbers only. Anything else causes BATMAN to hurl insults in
your direction (then again, so does any truly invalid parameter).
If you use a negative number, BATMAN ignores the negative sign
and uses the absolute value. Numbers greater than the limits of
your video screen will be ignored.
YORN
Gets either a 'yes' or 'no' response from the user. The nature of
the response can be a number of different variations. A value of
either zero or one is returned to ERRORLEVEL when the program
finishes. Zero means the user specified 'no' while a one
specifies 'yes'.
Valid 'yes' answers: YES, AYE, OK, OKAY, SI, OUI, DA, YEP,
FINE, 1, Y
Valid 'no' answers: NO, NINE, NYET, NEGATIVE, NAY, NIX, N
FILE(filename)
Processes BATMAN commands in a file. Commands are the same and can have
the BATMAN token on the front of the line (this makes for easy switching
from batch file line mode to command file mode).
filename: the name of the file containing the commands to process.
You must specify the entire file name, including path (if
other than current) and extension. I suggest using the
11
extension BM for BATMAN command files (see DEMO.BAT for an
example). No default file name extension is used.
BLANK
Clears the screen using the current text attributes. I included this to
avoid having to exit BATMAN just to clear the screen (You may also use
the command CLS, just like in DOS. This helps moving an old BATMAN batch
file to command file format). If you specify a text attribute before
using blank (say BACKGROUND(RED)) then the entire screen receives the
attribute.
BOX(x,y,height,width,horiz,vert)
Draws a box with border on screen using the current text attribute. I
included this since I included my windowing routines to handle BATMAN
errors in other routines. This is a quick way to put up fancy headers
and such.
x,y: The screen x and y coordinates with the upper left corner
being 1,1.
height: The number of total line tall the box will be INCLUDING the
top and bottom frame lines.
width: Same as above except how wide the box is.
horiz: The line type for horizontal lines. Must be either SINGLE or
DOUBLE. This will produce a line that is either a "─" or a
"═".
vert: Same as above except for vertical lines. Produces either a
"│" or a "║".
In all cases the lines convert to proper joining corners to match the
lines. The following BATMAN line produces a red box, with black letters
and double lines all the way around in the center of your screen. Try
it;
BATMAN foreground(black) background(red) box(10,10,60,5,double,double)
I welcome suggestions for more. Answers need not be in upper
case. They can be upper, lower or mixed case. Giving a response
other that one listed will tell the use that their answer is
ambiguous and to please enter it again. For now the message is
not very pretty and will cause screen roll if repeated. I'll fix
this in a later version. The fix will employ an error window,
color and a return of the cursor to it's original position.

PROBLEMS AND FUNDS:
Please report any problems you discover with BATMAN. This will
help with making the system batter in later releases. Anyone who
sends in a problem report and a blank disc (with return postage)
will get the latest release and bug fix free (if you are going to
the trouble to send in a report, don't forget the one dollar

COMING ATTRACTIONS:
I am already looking forward to version 1.2 of BATMAN. No release
date will be announced, but I suspect it won't be a month or two
following this. I would like any and all suggestions you may
offer. Credit for outstanding suggestions will appear in the
documentation.
I am considering adding the following features;
* The ability to SET environment variable with user response.
This would allow more control in batch files and allow
responses like 'A', 'B' or 'DONT-CARE' instead of just
numbers.
* Large letters. This would allow you to have a line of text
appear in letters larger than normal. May also consider
several different text styles, like Shadow or Old English.
* Support DOS commands which would normally require another
program. Mode was eliminated in this release (as far as
video was concerned). What else is useful, but requires a
separate program?
TECHNICAL ISSUES
BATMAN is coded entirely in Turbo Pascal 4.0. If something
doesn't work, then it's Borland's fault. I may toy around with
14
assembly language speed-em-ups later, but for now it's plain
vanilla.
The driving goals behind BATMAN were to keep the program small
and fast while making it easy to use. These goals are always at
odds with one another, so some compromises had to be made. The
worst one was the use of regular integers for parameters in the
BEEP command. It would have been elegant to specify tones as
musical scales (i.e. a symbol like 3C# for 'third octave C
sharp') and to have the durations and gaps in beats (say '1' for
a whole note and '4' for a quarter note, etc). However, lean and
mean beats fancy any day.
Source code is available upon request. Send one dollar, a blank
disc and return postage in a disc mailing envelope to;

You will get the souce code, documentation and object code for
the latest version of BATMAN. I welcome any criticism about
coding style and efficiency you care to offer.
