Maybe they were just Global Byte Pointers? OWG's were a late addition. I was a member of the FORTRAN-10/20 v10 project to make it generate/run code in extended addressing...

ISTR TOPS-10 getting new 8-bit I/O modes, but I have a vague recollection that translation between 36-bit words and mag tape frames was handled by the "tape formatter" hardware, which means that writing two words with 8 bit bytes in way that was easily legible on 8-bit byte oriented hardware ("high density mode" was only "legible" for the even words). phil
