==== FORTRAN programs ====

The VS FORTRAN compiler supports the Fortran 77 standard.

Create your source file with file type ''FORTRAN''.

     X EXAMPLE FORTRAN A

Compile your program:

     FORTVS2 EXAMPLE

Define standard load libraries: (Example is for load mode execution of temporary virtual memory copy of program executable. The following two commands only need to be executed once per CMS session.)

     GLOBAL TXTLIB VSF2FORT
     GLOBAL LOADLIB VSF2LOAD

Load your executable program into virtual memory:

     LOAD EXAMPLE

Run your program:

     START

==== To Save an Executable ====

Once you have a text file, you also make it into a ''MODULE'' file to be run multiple times:

      GENFORTV EXAMPLE
      
As this runs to make ''EXAMPLE MODULE'' from ''EXAMPLE TEXT'', it prints the commands to uses to give you understanding of the process.
