Damn, I was unaware of that. Hitting the docs now. Thank you Johnny.

Don't matter if any FP instructions are in the code or not. A couple of setup instructions are in the RTS initialization, unless you link with a version of the F77 library intended for code without FP.
The information on how to create a library that don't use FP is in the F77 manuals...

The 11/70's FP board set is flaky, and it has been removed pending repair. I had forgotten about that. But the "hello world"program shouldn't use any FP instructions..?
I don't think I can get over to LSSM today, but I will be working there tomorrow.

Error 2, by the way is usually for one of three reasons:
1. Task failed at the SVTK$S call (not able to install trap catching for various traps)
2. Task uses FP instructions, but task was build without /FP, or system lacks FP hardware support.
3. FCS initialization failure.
Most likely problem would be #2.

Hey folks, before I start digging into this, I figuredI'd ask here. A simple "hello world" program in F77 on RSX-11M-PLUS fails to start thusly:
$ run hello
TT3 -- Exiting due to ERROR 2
Task initialization failure
I was trying to move a larger FORTRAN program to this system (the 11/70 at LSSM) and it was dying with this message, so I wrote a quickie test case to narrow it down. It's just a write to unit 5:
WRITE(5,10)
10 FORMAT(' Hello World!')
END
...compiled with "FORTRAN HELLO", and linked with:
L HELLO,LB:[1,1]F77FCS/LIB
No warnings or errors. It runs fine on my 11/83 athome with a very similar config. Before I dig in, can anyone quickly point me to what I'm missing?
Thanks,
