I guess it is time to bring up the old example of the "variation of
constants", which used to work with the IBM compiler on MVS/ESA
the last time I tried it out (maybe 20 years ago):

      PROGRAM MAIN
      CALL SUB(3)
      PRINT *,3
      END
      SUBROUTINE SUB(I)
      I = 4
      END

This printed " 4", and, I hasten to add, is a fine example of what
*not* to do.  Compile this program with gfortran on Linux, and
it segfaults on execution.
