memset is part of the C library routines in /lib/libc.a.  At our installation
we are running UNIX BSD 4.2 and 4.3 on a Sun and VAX 11/750 respectively and 
both versions seem to have this routine in libc.a.  Here is what memset does
(as quoted from the manual page): 

char *memset(s,c,n)
char *s;
int c,n;

memset sets the first 'n' characters in memory area 's' to the value of
character 'c'.  It returns 's'.

There are two solutions to your problem:  1) Consult your local guru to
see if you have memset or a similar routine in one of the system libraries
(Sorry, but I'm not familiar with Pyramid).  2) Write your own little 
memset module (similar to the one below) in C and link it to all of the 
files which appear to be using it in the code.  From what I have observed,
arclzw.c, arcmisc.c, arcsqs.c are declaring the routine, but arcext.c is 
the only one that is actually calling it.  Good luck 8-).


char *memset(s,c,n)
	char *s;
	int c,n;
{
	register char *t;

	t = s
	while (n--)
		*t++ = c;
	return(s);
}
