/* Crude FORTRAN interface to C event logging routines.
   See evlog.c for more details.

   FORTRAN character variables are so unportable that guaranteeing
   that U can parse a variable length argument list is next to impossible.

   This provides very basic event logging functionality.

   CALL EVON()

      enable logging.

   CALL EVOFF()
 
      disable logging.

   CALL EVBGIN("event description")

      push event onto state stack

   CALL EVEND("event description")

      pop event off state stack

   CALL EVENT("event description")

      log occurence of event that doesn't change state stack
