I don't believe that Peter ever worked on the assembler or binder. On Mon, 18 Aug 2025 04:44:48 -0500 Paul Edwards <[email protected]> wrote:

That has nothing to do with whether the target module can be RMODE64. Similarly, if ATTACHX could not be invoked in AMODE 64, that would have nothing to do with whether the target can be AMODE64 (I think ATTACHX can be, but the point remains) :>>AMODE 64 and RMODE 64 do not require GOFF and do not require program object, IIRC. :>>RLD references, when appropriate, can be 8-byte.
