setting checkbreak to false won't entirely work.  Dos will still check
for break durring I/O processes just not at any other time.  Normally
dos checks more often than only durring I/O.  One way to dissable c-break
is with the command "ctty filename" this will cause dos to check for c-break
in filename instead of standard input(actually it changes standard I/O to
filename).  Add this command to the first line of your autoexec file.  But
be sure to add the command "ctty con" as the last line of your auto file.
If you don't do this standard I/O becomes filename and it is then impossible 
to type at the keyboard.  Also, you may have to spcifically write to "con"
inside your program because standard I/O has been changed.  Try it and find
out I haven't used it myself so I'm not sure.  Good luck let me know how it 
turns out.   8D
