Porting f77 code to f90

Hello,

I have got a fortran 77 code in unix. I need it to be ported to fortran 90 in unix. Can any one help me with this.

Thank you, Regards, Ajith.

FTN77 and FTN95 are not available for a Unix environment. In order to use either of these compilers you will need change to Windows.

Hi,

I have a fortran code which is compatible in unix. I need it to be migrated to a XP based machine using salford compiler. I have created a new project and added all the source files using the add existing item. I need to add some libraries(with .a extension and .sl extension) also, so i have added it in the project using the add reference option. When i try to compile the code its giving the following errors.

Compiling file: yn.f90 C:\ELLA Application\trip\src\yn.F90(1) : error 441 - Illegal character combination, '-' followed by '-' C:\ELLA Application\trip\src\yn.F90(2) : error 32 - Statement not recognised C:\ELLA Application\trip\src\yn.F90(3) : fatal 399 - Unrecognised statement, did you forget to add /FIXED_FORMAT?

Please find below a sample program which i am trying to compile...

Thank you, Ajith

Your code is in 'fixed' Fortran. You must either use the extension .for for your source files or use /FIXED on the FTN95 command line.

Libraries for a UNIX environment must be rebuilt. If you do not have the source code for the libraries (or equivalent Windows libraries) then it will not work.
