No, he's not.
My point was that with REXX you *can* do a substr(source,8,5) with a
source shorter than 13 bytes and REXX will pad the 3 characters from the
source with two blanks and *will assign* a 5 character string to the
target (varchar) variable.
So,with REXX the statement X = substr("1234567890", 8, 5) will assign
the string "890 " (2 trailing blanks) to variable X.
With PL/I, you get the compiler message I posted.
NOTE that I did not say PL/I is wrong. I (indirectly) said Shmuel's
statement was wrong.
I originally mentioned the REXX behavior and said that none of the other
programming languages I know offers the same functionality. It was in a
reply to this statement where Shmuel sparsely replied: PL/I
