I have a program listing in Fortran IV that I need to run.

Does anyone know a source of such compiler at a reasonable cost?

Thanks!!!

 
Just use Silverfrost, g95 or gfortran. They're all free.

Build it as a F77 program. The main difference is that some of the vendor specific stuff in FIV is now standard in F77. These are things like opening and closing files, direct access files, getting command line parameters and random numbers. Characters are new but the rest of it is the same.

If you get any compilation problems, post them here and someone will be able to point you in the right direction.
 
Few years ago, I compiled an old quantum chemistry code written in FORTRAN IV using f77 program.
 
Raghu81,

Do you happen to know which F77 package you used?

Thanks for your help!!!

 
I think you can try what xwb says, compile the code and post the error messages here.
 
g77 has now been replaced by gfortran: it will do F77, F90, F95 and possibly F2003.
