No way that I could find. I wrote this tiny prg to allow me to do it:


#include <stdio.h>
/*
	Return a random number between 1 and the argument given.
*/
main(argc,argv)
register int argc;
register char **argv;
{
	int i;
	long time(),random();

	srandom(time(0));
	i = atoi(*++argv);
	i = ((int)random() >> 4) % i;
	printf("%d\n",++i);
}

I use it to randomly select a .signature when I log in.

Randy
