These few lines of assembler do the job.
First, the keyboard status is checked; if there
is a keycode the program reads the code and return the ascii
portion, 0 otherwise. Does not work with function keys because
they generate an ascii value of 0 and can only be
distinguished by the scan code. (Yes, I know, not much
changes necessary, but I didn't need that feature :-).

Feed the following lines into debug (debug < file).
(Emtpy lines are intended - Don't leave them out.)

If you run testkey.com in a batch file and test for errorlevel 1 any key
pressed at that time makes the condition become true.

Example:

rem begin of autoexec.bat
echo press any key if you don't like to run WINDOZE
.
[stuff that takes some time to run]
.
testkey
if errorlevel 1 goto no_win
  win
:no_win
:end
