If it runs OK but only dies on exit, then it is very likely because the
DOS box isn't supporting all the old weird ways of a program exiting
and returning contol to DOS. You'd have to sit in a debugger to figure
it out, but I wouldn't be surprised if the program did an int 20h to exit,
or jumped directly back to DOS. Ugh.
But things might not be doing to hell 'till just after the program has
exited. You might want to try running this program in a batch file,
with something like echo ********* on the second line. If you
can see the results of the echo, then I could give you a teeny tiny
14 byte .com program which kills the DOS shell, which would at
least give you the ability to run the program and exist the dos shell
as soon as its done. I did just this many years ago for Win95
when a DOS app I wanted to run killed things but only after the
next program was run.
