Hi all,
I was wondering whether there is a prgramme that converts f77 to f90/95? Because I am about to get source code from a supervisor, and I know f90 but he's written it in f77 :(
 
Physics news on Phys.org


Most (all ?) f77 code is also legal f90. F90 just adds new features.
 


You don't say. So if I were to modify my supervisor's code, hopefully I shouldn't run into any errors regarding the differing versions of FORTRAN?
 


You can compile f77 in f90, you can't compile f90 with f77. Time only goes forward.
