But it doesn't leave room for the fullword.

Does a transitory negative offset from LOCCTR cause problems?
Even if no code is generated there?
But I'll persist in preferring my:
DS 1F
DS 0D
ORG *-4
o Fewer keystrokes
o Easier (for me) to understand.
But does the new-fangled ORG support something really fancy,
such as alignment to a multiple of 5 bytes?
