OpenVMS
On VMS you will need the DEC Fortran90 compiler installed and licenses loaded. This is available as part of the hobbyist project. These commands work for Fortran on both Alpha and VAX.
To compile, type the following at the DCL prompt:
$ FORTRAN HELLO.F
To link the file to the Run-Time Lib (RTL) type the following:
$ LINK HELLO.OBJ
To Run the executable image, type the following:
$ RUN HELLO.EXE Hello World! $
Enjoy all that VMS and Fortran offers.
