* Routine: PDVOUT - Parallel Version of ARPACK utility routine DVOUT
*
* Purpose: Double precision vector output routine.
*
* Usage: CALL PDVOUT (COMM, LOUT, N, SX, IDIGIT, IFMT)
*
* Arguments
* COMM - MPI Communicator for the processor grid
* N - Length of array SX. (Input)
* SX - Double precision array to be printed. (Input)
* IFMT - Format to be used in printing array SX. (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.
