SUBROUTINE TSUPMA	(IERROR)
C
C LATEST REVISION	 AUGUST	1984
C
C
C PURPOSE		 TO PROVIDE A SIMPLE DEMONSTRATION OF THE
C			 SUPMAP	AND MAPDRW ENTRYS OF EZMAPG.
C
C USAGE			 CALL TSUPMA (IERROR)
C
C ARGUMENTS
C
C ON OUTPUT		 IERROR
C			   AN INTEGER VARIABLE
C			 = 0 IF	THE TEST WAS SUCCESSFUL
C			 = 1 OTHERWISE
C
C I/O			 IF EACH CALL TO ROUTINE SUPMAP	RESULTS	IN
C			 A NORMAL SUPMAP EXIT, THE MESSAGE
C			   SUPMAP TEST SUCCESSFUL  . .	SEE PLOT TO
C			   VERIFY PERFORMANCE
C			 IS PRINTED ON UNIT 6.
C
C			 TEN CONTINENTAL OUTLINE PLOTS,	EACH
C			 RESULTING FROM	A DIFFERENT SPECIFIED
C			 PROJECTION, ARE PRODUCED ON THE MACHINE
C			 GRAPHICS DEVICE.
C			 TO DETERMINE IF THE TEST WAS SUCCESSFUL,
C			 IT IS NECESSARY TO EXAMINE THESE PLOTS.

C ALGORITHM		 SUBROUTINE TSUPMA CALLS ROUTINE SUPMAP	ONCE
C			 FOR EACH OF THE NINE PROJECTION TYPES
C			 IN SUPMAP.  SPECIFICALLY, THESE ARE
C			   STEREOGRAPHIC
C			   ORTHOGRAPHIC
C			   LAMBERT CONFORMAL CONIC WITH	TWO
C			     STANDARD PARALLELS
C			   LAMBERT EQUAL AREA
C			   GNOMONIC
C			   AZIMUTHAL EQUIDISTANT
C			   CYLINDRICAL EQUIDISTANT
C			   MERCATOR
C			   MOLLWEIDE TYPE
C			 THE ROUTINE THEN DEMONSTRATES THE SATELLITE VIEW
C			 PROJECTION.
