Jim,
I really like the way you handled my problem. After reading your code, I reliezed that what I needed to do was to not only check for semi-colons, but to only allow A-Z, 0-9, and space. Since this is what your code did, I rewrote my routine and would like you to throw rocks at it. I don't want to output any errors, only return to the calling routine.

Code:
#include<stdio.h>
#include<stdlib.h>
#include <ctype.h>
int sysrun(char *command) {
int num;
int m,pos;
char str[80];
char process[39] = "/gers/test/adhoc/syscr/wpleca2unix.sh ";
num=0;
for(m=0; (m<36)&&(command[m] != '\0'); m++)
  {
    char c=command[m];
    if(!(isalnum(c) || isspace(c)))
    {
      return 0;
    }
  }
strcpy(str,process);
strncat(str,command,35);
num = system(str);
return num;
}
