I will state the obvious. "no ill effects" that are observed does not mean that there are none, and certainly does not mean that the usage is supported. I surely hope that Ed is at least limiting this approach to SVC- and PC-entered services, not branch-entered. A service that is not documented as supporting AMODE 64 may choose to support AMODE 64 at any time and might choose an implementation that has a different interface than for AMODE 31 (basing its decisions on the AMODE of the caller). That could make a call such as this fail in obscure ways at an unexpected time. Is such an implementation all that likely? No. Possible? Yes.
