I used RT-11 versions 4 and 5, and I seem to remember the MACRO-11 there had .ASCIZ.

MACRO-11 on RSX-11D seems to ring a bell...

I first encountered it on RSTS/E 6C in the MACRO-11 it had... But the v6 macro assembler from DEC via Harvard that eventually wound up in 2BSD is older and dates to 1977 or so.
