However the definition of the JFCBX, to me at least, seems ambigous as to how I find the next JFCBX. There seem to be two fields, JFCBXTTR, which contains the SVA of the next extension block, and JFCBXNXT which contains the address of the next JFCB extension. Do these amount to the same thing? Which should I use?
For TTR/address fields, the address is normally filled in when the control block has been requested, and the link filled by the requester. That doesn't apply in your case, so use the SVA; even if the address is filled in and correct, the additional overhead for the SVA is typically a few dozen instructions.
