fortran versions 77,90,95

[ArmenD]

hi,
just wondering if newer fortran compilers like 95, or 90 are backwards compatible. for example, can i run f77 syntax in 90 and 95?

As far as I know, the answer: yes, you can.

g95 works on the filename extension. f, f90 and f95 map to Fortran 77, 90 and 95 respectively.

f77 to f90 conversions are possible, among the alternatives are...

perl script...
