If you need to test a facility bit >=32 *and* you might possibly be running on a pre-z9 machine(!) then first test bit 7 of the result stored by STORE FACILITY LIST to see if STFLE is available, and if it is then issue the STFLE instruction (if the output isn't already available somewhere) and test the bit from the list of bits stored. (More logic is required to ensure the bit you're checking is actually stored by STFLE; refer to Principles of Operation for details.) - mb -----Original Message----- From: IBM Mainframe Assembler List <ASSEMBLER-LIST@LISTSERV.UGA.EDU> On Behalf Of Ed Jaffe Sent: Friday, March 4, 2022 12:53 PM To: ASSEMBLER-LIST@LISTSERV.UGA.EDU Subject: [EXTERNAL] Re: Long Displacement Facility (was: Fun with RXSBG) On 3/4/2022 9:31 AM, Dave Clark wrote: > "IBM Mainframe Assembler List" <ASSEMBLER-LIST@LISTSERV.UGA.EDU> wrote on > 03/04/2022 12:19:51 PM: >> IIRC, STFLE is newer than the Long Displacement Facility.
