The only thing we really used on RSTS was Basic Plus so I wouldn’t know, but I spent a lot
of time making cross calls between MACRO-11 and FORTRAN on the RSX-11M and there was no
MARK-based linkage in anything I saw. I had the kind of odd misfortunate to spend one
summer in college writing a database system in Fortran and Macro-11 on RT and when I
graduated the company saw that and set me down to work on FORTRAN/MACRO-based database on
their two processor RSX-11M system.

RSX-11 probably used it, though, as could've RSTS...
