This was true even in the 1960s for the first versions of PL/1. A lot later than that, try the 70s. PL/1 F level subroutine calls did a getmain/freemain for each subroutine call. Too much overhead to call even one subroutine for each of 30K records on a 360/91 & MVT. ---------------------------------------------------------------------- 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
