USER-FORMAT-ROUTINE

   The user-written USER-FORMAT-ROUTINE performs format operations.
   The symbiont's control logic routine calls your format routine
   at one of two possible points within the symbiont's execution
   stream. You select this point by specifying one of two routine
   codes when you call the PSM$REPLACE routine.

   A user format routine can be an input filter routine (routine
   code PSM$K_INPUT_FILTER) or an output filter routine (routine
   code PSM$K_OUTPUT_FILTER). The main format routine (routine code
   PSM$K_MAIN_FORMAT) cannot be replaced.

   A user format routine must use the call interface described here.
