4621.0. "Need PDP-Alpha Fortran Converter" by MSDOA::CLICK () Tue May 28 1996 14:51

    If you know of a PDP11 Fortran converter to Alpha/OpenVMS/Fortran 90, I
    may have a prospect who needs just that.  If you wish to contact me
    directly rather than answer here, my phone is 919-493-0100.  Prospect
    is located in North Carolina.

	There is very little if any conversion necessary. All the language elements are supported. If PDP-11 specific I/O or error routines (FDBSET, ERRSET, etc.) are used, some modification may be necessary. Use the /NOI4 switch to get default two-byte integers. See http://quark.zko.dec.com/fortran/migrating-fortran.html if the program uses RAD50 routines and constants. Ask for help on specific issues in TURRIS::FORTRAN. Basically - just try it - you may be pleasantly surprised. Steve
4621.2	90% of the iceberg is below the surface	MSDOA::GUIDRY	Ghost Rider	`Tue May 28 1996 17:04`	13
	Re: .0 On PDP-11's, FORTRAN IV was used for many things, ranging from straightforward data processing programs to real time systems. You didn't say much about the original PDP-11 FORTRAN programs. If they are simple, then .1 is right on. If they are part of more complex system, then you may need to reengineer the system (Newer operating systems work differently than RSX11M and RSTS). This would be more complex than a simple code translation. Consider selling them some SI time and having someone look over the situation.

	Thanks for .1 and .2; I'll discuss with the prospect hopefully tomorrow. Don
