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. > On Jan 5, 2016, at 6:24 PM, Dave Horsfall wrote: > > On Mon, 4 Jan 2016, Ronald Natalie wrote: > >> Just never figured out how to make good use of the MARK instruction on >> the PDP-11. > > RSX-11 probably used it, though, as could've RSTS... -------------- next part -------------- A non-text attachment was scrubbed...
