	You tried to do a system("chkdsk") and it worked??? I don't
understand. I have gotten chkdsk errors when I try even a small program:

int main() {
	system("chkdsk");
}
Chkdsk runs, but causes errors. When I do this directly from command.com
it works.

	As above, my program is a shell program. So the user enters a command.
and then I call system to run it (for now). so for example:

while (key!=return_key) {
.....
getche(); 
} // A string is being created in this loop based on input

system(command);
// Where command is the string created in the above while loop.

I believe you mentioned earlier that a DPMI swap file is opened and this
might cause the error. Is there any way for me to close the swap file
temporarily and reopen it after the system call?

Thanks,
	Paul
