I don't know how to connect absoft fortran with star-cd. Every time when I try to compile subroutines, star-cd writes "f77 - is not name of internal command" or "lnk is not a name of ...". Of course nothing is compiled...

Where am I wrong and what should I do to make this work)?

Best Regards

To you type that inside of Prostar? Make sure that your path variable contains the fortran binary path. Check it with "which f77". Then try starlink from the prompt. Hope that helps.
