+      SUBROUTINE TPWRZT	(IERROR)
+C
+C LATEST REVISION	 JULY, 1984
+C
+C PURPOSE		 TO PROVIDE A SIMPLE DEMONSTRATION OF
+C			 PWRZT IN CONJUNCTION WITH THREED.
+C
+C USAGE			 CALL TPWRZT (IERROR)
+C
+C ARGUMENTS
+C
+C ON OUTPUT		 IERROR
+C			   AN INTEGER VARIABLE
+C			   = 0,	IF THE TEST IS SUCCESSFUL,
+C			   = 1,	OTHERWISE
+C
+C I/O			 IF THE	TEST IS	SUCCESSFUL, THE	MESSAGE
+C
+C			   PWRZT TEST SUCCESSFUL  . . .	 SEE PLOT
+C			   TO VERIFY PERFORMANCE
+C
+C			 IS PRINTED ON UNIT 6.
+C
+C			 IN ADDITION, ONE FRAME	CONTAINING THE
+C			 CHARACTER PLOT	IS PRODUCED ON THE
+C			 MACHINE GRAPHICS DEVICE.  TO DETERMINE
+C			 IF THE	TEST IS	SUCCESSFUL, IT IS NECESSARY
+C			 TO EXAMINE THIS PLOT.
+C
+C PRECISION		 SINGLE
+C
+C REQUIRED LIBRARY	 PWRZT,	THREED
+C FILES
+C
+C
+C LANGUAGE		 FORTRAN
+C
+C ALGORITHM		 TPWRZT	CALLS SUBROUTINES SET3 AND LINE3 FROM
+C			 THE ULIB THREED PACKAGE TO ESTABLISH THE
+C			 THREE SPACE-TO-TWO SPACE TRANSFORMATION
+C			 AND TO	DRAW AXIS LINES.  TPWRZT NEXT CALLS
+C			 SUBROUTINE PWRZT FROM THE ULIB	THREED
+C			 PACKAGE TO LABEL THE AXES FOR A THREE SPACE
+C			 PLOT.

+C SUBROUTINE PWRZ IS USED TO LABEL EACH	OF THE AXES AND	THE PLOT
+C ON INPUT TO PWRZ,
+C THE FIRST THREE PARAMETERS AND ICNT DETERMINE	THE POSITION OF	THE
+C CHARACTER STRING.
+C ISIZE	DETERMINES THE CHARACTER SIZE.
+C LINE AND ITOP	DETERMINE THE DIRECTION	AND PLANE OF THE CHARACTERS.
