C
C                  B L A S Subprogram
C  Description of Parameters
C
C  --INPUT--
C          N  number of elements in input vector(s)
C         CB  complex scalar to be added to inner product
C         CX  complex vector with N elements
C       INCX  storage spacing between elements of CX
C         CY  complex vector with N elements
C       INCY  storage spacing between elements of CY
C
C  --OUTPUT--
C     CDCDOT  complex dot product (zero if N .LE. 0)
C
C   Returns result with dot product accumulated in D.P.
C     CDCDOT = CB + sum for I = 0 to N-1 of CX(LX+I*INCY)*CY(LY+I*INCY)
C     where LX + 1 if INCX .GE. 0, else LX =(-INCX)*N, AND LY IS
C     defined in a similar way using INCY.
