C***DESCRIPTION
C
C B L A S Subprogram
C Description of Parameters
C
C --Input--
C N number of elements in input vector(s)
C SA single precision scale factor
C CX complex vector with N elements
C INCX storage spacing between elements of CX
C
C --Output--
C CX scaled result (unchanged if N .LE. 0)
C
C Replace complex CX by (single precision SA) * (complex CX)
C For I = 0 to N-1, replace CX(IX+I*INCX) with SA * CX(IX+I*INCX),
C where IX = 1 if INCX .GE. 0, else IX = 1+(1-N)*INCX.
