Try this instead of using embedded perl (which probably defeats the purpose of the exercise):

#!/bin/sh
length=`echo  $string | wc -c` # Thanks OZO
reverse=`echo $string | rev` # Note that the rev command is available on HP-UX 11.0
if [ $string = $reverse ]
then
     echo $string is a palindrome
else
      echo $string is not a palindrome
fi
Thanks,
--Aditya.

This question was awarded, but never cleared due to the JSP-500 errors of that time.  It was "stuck" against userID -1 versus the intended expert whom you awarded.  This corrects the problem and the expert will now receive these points; points verified.
