*-----------------------------------------------------------------------
* Routine: CVOUT
*
* Purpose: Complex vector output routine.
*
* Usage: CALL CVOUT (LOUT, N, CX, IDIGIT, IFMT)
*
* Arguments
* N - Length of array CX. (Input)
* CX - Complex array to be printed. (Input)
* IFMT - Format to be used in printing array CX. (Input)
* IDIGIT - Print up to IABS(IDIGIT) decimal digits per number. (In)
* If IDIGIT .LT. 0, printing is done with 72 columns.
* If IDIGIT .GT. 0, printing is done with 132 columns.
