+      SUBROUTINE TDASHL	(IERROR)
+C
+C LATEST REVISION	 APRIL 1984
+C
+C PURPOSE		 TO PROVIDE A DEMONSTRATION OF DASHLINE
+C			 AND TO	TEST DASHLINE ON A SIMPLE PROBLEM
+C
+C USAGE			 CALL TDASHL (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			   DASHLINE TEST SUCCESSFUL  . . .  SEE	PLOT
+C			   TO VERIFY PERFORMANCE
+C
+C			 IS PRINTED ON UNIT 6.
+C
+C			 IN ADDITION, ONE FRAME	CONTAINING THE
+C			 DASHED	LINE 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 ALGORITHM		 TDASHL	UTILIZES THE SOFTWARE DASHLINE
+C			 SUBROUTINES DASHDB, FRSTD, VECTD, LINED AND
+C			 CURVED	TO DRAW	FIVE CURVES ON ONE PICTURE
+C			 USING FIVE DIFFERENT DASHLINE PATTERNS.  EACH
+C			 CURVE IS CENTERED ABOUT SOLID AXIS LINES AND
+C			 LABELLED WITH THE BINARY REPRESENTATION OF THE
+C			 DASHLINE PATTERN USED.

+C PORTABILITY		 FORTRAN 77
+C
+C X CONTAINS ABSCISSAE VALUES OF THE CURVE TO BE PLOTTED, Y CONTAINS
+C COORDINATE VALUES OF THE CURVE TO BE PLOTTED.
