Here's my problem: I have the following program (tst.c) that
I compiled with djgpp v.2 patchlevel 3:

#include <stdio.h>
main() {printf("Test\n");}

I then create a batch file with the line: tst >tst.out
repeated about 100 times. After about the 55'th line, I get
the message:
"Warning: cannot open swap file c:\tmp\cwsdpmi.swp"
After that, trying to run any command just gives the
error message: "Too many open files in system (ENFILE)"
They system must be rebooted to return to normal operation.
I am running MS-DOS ver. 6.20, with FILES=60.

It looks as if the program opens a file handle every time, and
never releases is when the program exits. Just wondered if
anyone else has run into this problem, and if so, is there
a way around it?
