Y-N.DOC THIS FILE
Y-N.ASM THE ASSEMBLER SOURCE CODE
Y-N.COM THE WORKING COM FILE
Y-N-TEST.BAT FOR TESTING Y-N

The program is patterned after a program written by John Lewis
using C. That program has a .COM file about 3.7k in size. This
program was written in order to duplicate the function of the
C version while reducing the size of the .COM file. The intent
was to produce a .COM file that loaded and executed faster. The
goal has been met. As an added benefit the program can easily
be modified to conveniently handle other responses if desired.

----------------------------------------------------------------
For anyone who may be in the dark after reading that vague bit
of documentation, Y-N is a program you can run from a batch
file. The format for the command is:

Y-N [prompt string]

where [prompt string] is any yes/no question, such as, "Do you
really want to do this?" Y-N echos the prompt string and pauses
for a Y/N input from the keyboard. It sets ERRORLEVEL to 1 if
the keyboard input is Y and sets ERRORLEVEL to 0 if the keyboard
input is N. You can use the batch file command IF ERRORLEVEL
[number] to branch to two different sets of commands, depending
on the input to Y-N. A sample batch file has been included in
the ARChived file. This user thinks it's rather handy.

Have fun!
