<snip>On page 199 I can see V() references in the RLD.Where are VD() references
documented?</snip>
There is no 8-byte V-Con (a la "VD").There is an 8-byte A-con ("AD") and that
can be used in conjunction with an EXTRN statement for an external reference,
just as a 4-byte A-con can be used in conjunction with an EXTRN statement for
an external reference.
<snip>Since RMODE is not documented for ATTACHX, RMODE64 is not supported.
Therefore, R14 will never be above the bar (64 bit address). First and
foremost, it says R14 is "return address" which implies R14 will always be a
valid address regardless of the AMODE. </snip>False. That says you must not
invoke ATTACHX in RMODE64. 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. There is an "extended" bit
that is on, in addition to the normal bit(s) that might indicate 2, 3, 4-byte.
