Maybe not. I think Shmuel was right to assume that if BCD was lower case only that TSO would have converted everything to lower case just as in fact it converts everything to upper case. Why would it do that? My guess is to make it easier. I did say "a bit easier". If I was coding a parser today, I'd probably copy the input line to another area, translate the copy to all upper (or lower) case and parse, then extract data from the untranslated copy. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
