<snip> Perhaps you don't understand what I mean by "blanket statement": a single affirmative sentence in the Introduction to the manual, "Any service described herein may be invoked from a location below 2 GiB." </snip>
Do you think there is anyone in the IBM world who needs that sentence? It might be thought that things prevalent by MVS/XA (the late 70's) are "known" and need not be stated. Regardless, such a statement is not what I read your previous post to suggest. <snip> >> VERY FEW system services officially support invocation in RMODE 64. If >> they don't say that they do, then do not assume that they do. >> ... Is there a blanket statement to this effect in the relevant manual(s)? </snip> To me, that asks about a negative statement. Such a statement might have been "No service may be invoked from a location >= 2G unless it explicitly is documented that it allows that". As I mentioned previously, we do not typically have such negative statements. I would be OK with adding an RMODE section (which could describe to the "Using the Services" section of each of the MVS [Authorized] Assembler Services References if you request that that be done by a note to MHVRCFS. But those books cover only a small portion of the z/OS programming interfaces. Many other macros and services have far less environmental information. That's not a good thing. But I have no leverage to get it improved. They rely far more heavily than the MVS books do on "if we don't tell you it's OK, then assume you can't". For example, they don't bother saying "it is OK to be in primary ASC mode". Because that's all there was at the time these books were written. It "goes without saying" so they don't say. So maybe what you really want to suggest is that there be a place that applies to all of z/OS where such "global" information for interfaces could be put.
