Give me some time (tomorrow perhaps), and I'll check in the manuals. I think the RSX manuals also holds how to install on RSTS/E. Johnny Bob Armstrong skrev: Does anybody know the procedure for installing F77 v5.4 on RSTS/E 10.1? @[0,1]INSTAL doesn't seem to work for that. There's a F77 v5.2 manual on Bitsavers, but the RUN $BUILD procedure that it recommends also doesn't seem to work for F77 v5.4.
