Fortran to C compiler

[nphani]

Hi Friends,

I have a C compiler and have been using "f2c" to convert F77 programs to C and later using my C compiler. Now, I also have F90 programs. I get errors when using f2c to convert them to C. Does f2c support F90 to C? Else, do we have any other converters that can do this?

I have seen some Fortran 77 to Fortran 90 converters, but none doing the reverse. Does anyone know about any converter converting F90 to F77?

Any help would be highly appreciated.

f2c doesn't support F90 to C. In fact, F90 is almost like C with a different syntax and extra facilities like BLOCK DATA and NAMELIST.

F90 to F77 isn't that easy. F90 has a lot of stuff that doesn't exist in F77 like structures, recursion etc.

Sorry about the negative tone.
