Hm. I thought there was a way to compile Fortran with different libraries for either no FPP (software libs) or EIS/FIS (for the 11/35,40 systems).

Yes, I have that install-media as well. I didn't look at it and assumed it
would have the same problem.
I may take a look at that instead, then. Until I get a KEF11-A for my CPU.

Thanks!

Does RSX have the equivalent of the FORTRAN-IV compiler on RT11?  That one
is a more basic implementation, lower performance but I think also smaller
code.  It doesn't need an FPP.

Well darn! I forgot I don't have the KEF11-A chip installed so Fortran
programs don't run on my 11/23-PLUS.
I have seen one for sale but it is rather expensive at almost $400.....
Guess I'll have to keep an eye out.

I'll give the tapedup code a try on my PiDP-11 instead.

Hi Jon,

Next I am going to attempt to compile your tapedup utility and see how
that
goes. I have never written or compiled
anything in Fortran77 before so it will be interesting.

Unfortunately, I didn't see a compile and link command file
to link the tapedup program with mtape, and my memories of
RSX-11M have been overwritten with VMS stuff.  Hopefully,
you can find some docs online for running the link step.

Jon
