Wow -- I was impressed at how code can expand to fill available
space.

When I found I needed to have a copy of touch on a ms-dos system when
I first needed one, I whipped this up in a few minutes (it has no c or f
options) --

/* File: touch.c - created by Marty Leisner */

/* something like unix touch */

#include <stdio.h>
 
main(argc, argv)
int argc;
char *argv[];
{
        while(--argc) {
                argv++;
                if(utime(*argv, NULL))
                        printf("can't update file %s\n", *argv);
        }
}

I first used open and close on the files (which I believe forces a dos 
timestamp, but then I found out Aztec supports the utime function.

It did the job.
