>Will the ETDEAM bit support be retrofitted to earlier >z/OS levels? The earlier the better for me. As with almost everything considered for retrofitting, it would likely require a significant business case to make it happen, unless it was documented that it worked (i.e., documented to work, but did not work) in which case an APAR would be considered. Dare one ask what's the big deal? Can't you just place SAM64 as the first instruction of your PC routine and get the same affect (aside from the additional cycle(s) for the instruction)? Peter Relson z/OS Core Technology Design ====================================================== As I mentioned in another message, the extended addressability guide says z/OS V1R3 supports the ETDEAM bit. My PC routines must run on OS/390 2.10 (31-bit box), as well as z/OS, so they cant have SAM64 as the first instruction. Instead, when I create the entry table I check for HBB7708 (V1R5) and set the ETDEAM bit. The PC routines are written to tolerate either addressing mode, but if the caller is AM64 and calls my PC routine without the ETDEAM bit ON, then the caller gets a program check. Jeffrey D.
