>"Standard" save area???? Now what on Earth does that mean... z/OS Doc, as does z/OS itself, has compatibility requirements. Standard save area means what it has meant for 40 or 50 years. Unfortunately, that leads reasonably to questions like yours since of course now the word "standard" in this context has no intrinsic (only historical) meaning.
>in the ATTACHX doc in "Reference", and all that said was >that R13 contained the "Address of a standard save area". This was apparently updated in z/OS 2.1 (as it is correct in the z/OS 2.1 knowledge center). While I fully sympathize and empathize with wanting to use the z/OS 1.13 books because they're still available via bookmgr (and I frequently do so myself), it can still be important to look at the current books. >> I believe at the Z level it became 144. >But note >,ETXR=exit rtn addr >The contents of the GPRs when the exit routine receives control are as follows: >Register Contents >... >13 Address of a 72-byte area provided by the system. There really is no "but" since there is no conflict between the two. "It" referred to the register save area provided to the attached routine (which does get a 144-byte save area). The ETXR is a different matter. IRBs (and the ETXR is one) do not in general get a 144-byte save area. ATTACHX processing was changed from providing a 72-byte savearea in or before z/OS 1.4, but after OS/390 R10.
