[comp.sys.mips] how does one debug fortran programs

sandrock@aries.scs.uiuc.edu (Mark T. Sandrock) (11/29/90)

Is it really true that the f77 compiler cannot produce a numbered
listing of the input source code? I sure can't figure out how to do
that. The -edit option looked quite promising, but it refuses to work.
When I specify -edit I receive a warning message:

$ f77 -edit access.f
f77: Warning: -edit ignored for background compile in non-X environment
^C

Thinking it might have to do with the fact I use ksh, I tried again after
invoking csh, but received the same warning message.

Nor could I find an explanation for the various compiler warning messages
I was seeing when attempting to compile a large Fortran program.  (There
is only an explanation for runtime error messages in the f77 manual.)

Thanks in advance for any advice.
