Isn't a STEPLIB opened before the program is loaded? Does the DCB used in that open override the JCL and/or the DSCB?

IEFBR14 has (effectively) two instructions: SR 15,15 BR 14 NO open. >(But did I really test what I thought I tested?) I don't think so, there used to be a minimum BLKSIZE of 18, but that's not detected until you try to open the DSN. No open; no error. IEFBR14 does no open. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
