I'm so glad to give my feedback on this issue. I use an older version pl/i compiler to recompile the pl/i program and after that my job just finished in two minutes!
So the problem lies in compiler. As for qsam and bsam, I don't know how to generate a dump and check it. I'll do some research to verify. On 8/27/06, Robert A. Rosenberg <[EMAIL PROTECTED]> wrote:

It was just a SWAG (Scientific/Stupid Wild Ass Guess) analysis on my part. Sometimes you just hit on the right answer just from the symptoms for no other reason. I'd be interested in follow-up (just for my own information) once you verify if I was right or not. If you want to check on if QSAM or BSAM is in use, just take a System Dump while the program is running and look at the DCB in the dump. ---------------------------------------------------------------------- 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
