Yes muntfish I did create a typo when submitting to perlmonks. 
    return (0 eq system "$KSH_SCRIPT"?$1:2);

should be... 
    return (0 eq system "$KSH_SCRIPT"?1:0);

Using your advice and changing my paran's made it work: 
    return (0 eq system "$KSH_SCRIPT")?1:0;

All is well now. Interestingly enough both "eq" and "==" work as expected on testing the return code. I assume it comes back as an integer and perl converts for us? Thanks for the help!!
