Re: oldie but goody

Talk about a blast from the past! It's "Back To The Future!" I don't suppose you remember what the system call was for time-of-day when you were doing Fortran on the 360? Sorry, that was 1976-77 and my JCL and FORTRAN IV are getting a bit rusty. But here is the manual: http://bitsavers.trailing-edg...

Re: oldie but goody

One thing that may be helpful is to give: //class=P, time=1440 because on an IBM mainframe, a job with more than 200K RAM requires special permission (class =p means high priority) and time=1440 means let the job run as long as it takes, because the job gets a forced timeout when the time limit is ...

Re: oldie but goody

A horrifying thing about FORTRAN IV is that only the first two letters in a variable name are recognized. so: JIVE =1 JIM = 2 both represent the same variable. The easiest way to keep track is simply to not use variable names longer than two letters. I'm not sure about that. Look at page 21 (on the...

Re: oldie but goody

I used to run a fortran iv compiler on IBM 360 and 370 hardware in the late 1970s. You will need: // exec fortfclg for execute fortran (f) compile, link, go I don't remember if the F is for fortran (f)our or if it was the (F) version of the compiler. Very close. FORTGCLG as it turns out. I actually...

Re: oldie but goody

I actually got it to compile using f77 (part of gcc project) many years ago when (I think) the source was released. But I think that was the more current version, not the version 6 stuff... Yes. If a legacy compiler (or even an f77 with legacy switches) can be found, it would make it "easy". I've b...

Re: Oldie but goody.

Hello: [...] Self-evidently, the level of effort might be reduced if we could but find a Fortran IV compiler. But where? Maybe here. http://www.bsp-gmbh.com/turnkey/herc_mvs.html This distribution of IBM's MVS 3.8 runs on a Hercules emulator (Cygwin or Linux). This version might have IBM's "Fortran...

Re: oldie but goody

I will warn you: they are NOT easy to find. If Fortran only required type declarations for all variables, it would be pretty easy. But with the "implicit" declaration (IE implicit integer a-z) we are pretty much screwed. Each piece will have to be debugged pretty much line by line since it won't pr...
