CONCC

       SUBROUTINE  CONCC (Z1,ZE,Z2, MX,MY, NX,NY, NZ, PL2OR3)
 C$    (Contour A Complex Function)
 C$    Draw contours for a  complex function.  Solid contours  are
 C$    drawn for the absolute value,  and dashed contours for  the
 C$    argument.  The arguments are:
 C$
 C$    (MX,MY)    Actual declared dimensions of Z(*,*)
 C$    ZE(NX,NY)  Array of complex function values
 C$    Z1,Z2      Range of absolute values
 C$    NZ         Number of contours of absolute value (.GT. 1)
 C$               (the  argument   is  contoured   at  30   degree
 C$               intervals from -180 degrees to 180 degrees)
 C$    PL2OR3     2-D  or  3-D  pen  movement  subroutine, perhaps
 C$               PL2CA or PL3CA.   If 3-D plotting  is in  effect
 C$               (set via CALL SET3D  (.TRUE.)), the 3-D  version
 C$               must be  used.   Otherwise the  2-D  version  is
 C$               required.
