  35.           In TPU, there is a routine called CALL_USER, which allows
  36.           you to run an external (non-TPU) subroutine that is
  37.           user-written (well, actually, programmer-written) in a
  38.           regular VAX programming language, such as FORTRAN, C, or
  39.           BASIC.  The name of the external routine is TPU$CALLUSER.
  40.  
  41.           The TPU_CALLUSER package is a general-purpose implementation
  42.           of the TPU$CALLUSER routine.  Instead of having one
  43.           designated function, or a predeterminied set of functions,
  44.           the TPU_CALLUSER package allows the TPU user to call
  45.           subroutines in system libraries (or any other shareable
  46.           image libraries) on the fly.
