You are at risk in using the "address" of the JFCB in the TIOT. It might be an address and it might not. It IS however always a "SWA virtual address token." Pass it to the SWAREQ macro (probably documented in Authorized Macros but does not require authorization) and voila! Get back an address you can depend on.

Kripke Sent: Tuesday, May 25, 2010 2:31 AM To: IBM-MAIN@bama.ua.edu Subject: JFCB PREFIX QUESTION Hello; I was curious what the 16 bytes in front of the JFCB is. I extract the 3 byte ADDRESS of the JFCB from the TIOT, and, then need to step past a 16 byte area in front of the actual JFCB. What is contained in the 16 byte area? I have tried to make some sense of it. ---------------------------------------------------------------------- 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
