ROTF,LMAO! if it's RMODE64 then it is required to be AMODE64, so no new rule is required for R15.

Incorrect, the doc clearly says AMODE64 (not RMODE64). I wonder how IBM handled the transition of existing AMODE64 programs. When the subtask routine is to run in 64-bit addressing mode, it is expected to use relative branching and register 15 contains a value that can be used to determine the addressing mode of the issuer of the ATTACH or ATTACHX macro as follows: Issuer AMODE 24: X'FFFFF000' Issuer AMODE 31: X'FFFFF002' Issuer AMODE 64: X'FFFFF004' ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
