I'm in the 255 camp and just tried a simple experiment. From TSO issue the Edit command: E T(ABC) CL
This opens the old editor on dataset t.clist member abc and after adding a few records and saving I checked the dcb which was VB,255,3120 Not the ideal blksize but the lrecl is what I expected. hth -------------------------------------------------------------------------- Lionel B.

Clearly, the intent was to allow up to 255-character source lines. At PSI, we provide the option for customers to allocate our CLIST/EXEC libraries either RECFM=FB w/LRECL=80 or RECFM=VB w/LRECL=259. One customer claims the industry-standard for RECFM=VB CLIST/EXEC libraries is LRECL=255 rather than LRECL=259. LRECL=255 would allow for only 251-character source lines, which seems rather strange to me. Of course, my personal observations and experiences provide nothing more than anecdotal evidence. Like a man with two watches being unsure of the time, I am now unsure if LRECL=259 is widespread practice or if I was observing only outliers. Any insight would be appreciated... -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 http://www.phoenixsoftware.com/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
