Well, since -F is a optional parameter, and the only place it was 
initialized was in the getopt switch, I think the initialization to 
NULL serves a purpose when I'm checking if script is NULL or not to 
decide if further processing of it is to be done.

Example:
#include <stdio.h>

int
main (int argc, char **argv)
{
         char *cp1;
         char *cp2 = NULL;

         printf ("cp1: %p\ncp2: %p\n", cp1, cp2);
}

Output:
cp1: 0xbfbfed34
cp2: 0x0
