+C
+C LATEST REVISION	 JUNE 1984
+C
+C PURPOSE		 TO PROVIDE A SIMPLE DEMONSTRATION OF
+C			 CONRECQCK AND TO TEST CONRECQCK ON A SINGLE
+C			 PROBLEM
+C
+C USAGE			 CALL TCNQCK (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 THE	TEST IS	SUCCESSFUL, THE	MESSAGE
+C
+C			   CONRECQCK TEST SUCCESSFUL  .	. . SEE	PLOT TO
+C			   VERIFY PERFORMANCE
+C
+C			 IS PRINTED ON UNIT 6.
+C			 IN ADDITION, TWO FRAMES CONTAINING THE	CONTOUR
+C			 PLOT ARE PRODUCED ON THE MACHINE GRAPHICS
+C			 DEVICE.  IN ORDER TO DETERMINE	IF THE TEST
+C			 WAS SUCCESSFUL, IT IS NECESSARY TO EXAMINE
+C			 THESE PLOTS.
+C
+C PRECISION		 SINGLE
+C
+C ALGORITHM		 THE FUNCTION
+C			   Z(X,Y) = X +	Y + 1./((X-.1)**2+Y**2+.09)
+C				    -1./((X+.1)**2+Y**2+.09)
+C			 FOR X = -1. TO	+1. IN INCREMENTS OF .1	AND
+C			     Y = -1.2 TO +1.2 IN INCREMENTS OF .1
+C			 IS COMPUTED.
+C			 TCNQCK	CALLS SUBROUTINES EZCNTR, CONREC, AND
+C			 PWRIT TO DRAW TWO LABELLED CONTOUR PLOTS OF THE
+C			 ARRAY Z.

+C THE INTEGER COORDINATES RANGE	FROM 0.0 TO 1.0, THE VALUES TX AND TY
