Not necessarely. Suppose You doing (want to do!) an essentially character compare. Like: x1 = x2 where e g x1 = 'AB' and x2 = 'CDE' etc.
Now You have x1 = '1' and x2 = '01'. Doing the compare x1 = x2 will get the result that they are equal, becuase REXX is doing a numeric compare. You can aviod this with having the compare of: 'A'||x1 = 'A'||x2 etc. Or using the form: x1 == x2 (note the double equals).
