Invokes the VSI BASIC for OpenVMS I64 compiler.

   Format:

      BASIC [/command-qualifier]... {source-file [/file-qualifier]... }...

   When you supply one or more file specifications, the compiler  compiles  the
   source file(s).

   If you  separate  source  file  specifications  with  commas,  the  compiler
   compiles  each module separately and produces multiple object files.  If you
   separate source file  specifications  with  plus  signs  (+),  the  compiler
   appends the files and produces a single object file.
