    To my fellow C nerds,

    It's been a  great manny years since I wrote this appended

    In short,, can anyone 'splain why strtok needs all this?



I don't think you need the copies.  This works just as well:

#include <stdio.h>
#include <string.h>

  char *bp, *tok;
  char *delim=" ", s1[256]="abc def ghi jkl mno.";

  while ((tok = strtok(bp, delim)) != NULL)
    bp = NULL;
    printf("tok = [%s]\n", tok);

Ooops ... wasn't paying attention.  While the printed output is the same, doing
it this way is destructive to the original s1 string - which may matter (or
