   3: **  IIGLOBALS.H -- Equel run-time library globals
   4: **
   5: **	In this file are defined the global variables,
   6: **	and manifest constants used in the Equel run-time
   7: **	routines. All globals must start with "II".
   8: **
   9: **	Requires:
  10: **		The "pipfrmt" structure is the ingres interprocess
  11: **		pipe buffer structure defined in ".../pipes.h".
  12: **		MAXDOM is defined in .../ingres.h.
  13: **
  14: **	Required By:
  15: **		.../source/equel/II*.c
  16: **
  17: **	History:
  18: **		Worked upon at various times by :
  19: **		jim ford
  20: **		eric allman
