CICS uses an SVC and is also defined as a subsystem. Telling CICS which SVC to use is simple. How can I have two versions of the subsystem code DFHSSIN running? Do I need to have two versions, or can I use one version of DFHSSIN (the new one or the old one), TIA Gadi ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- 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
