Function/Subroutine Documentation

subroutine upc	(	character*(*)	CHR,
			NCHR,
		dimension(*)	IBAY,
			IBIT,
		logical	CNVNULL
	)

THIS SUBROUTINE UNPACKS AND RETURNS A CHARACTER STRING OF LENGTH NCHR CONTAINED WITHIN NCHR BYTES OF IBAY, STARTING WITH BIT (IBIT+1).

ON OUTPUT, IBIT IS UPDATED TO POINT TO THE LAST BIT THAT WAS UNPACKED. NOTE THAT THE STRING TO BE UNPACKED DOES NOT NECESSARILY NEED TO BE ALIGNED ON A BYTE BOUNDARY WITHIN IBAY.

USAGE: CALL UPC (CHR, NCHR, IBAY, IBIT, CNVNULL) INPUT ARGUMENT LIST: NCHR - INTEGER: NUMBER OF BYTES OF IBAY WITHIN WHICH TO UNPACK CHR (I,E, THE NUMBER OF CHARACTERS IN CHR) IBAY - INTEGER: *-WORD PACKED BINARY ARRAY CONTAINING PACKED CHR IBIT - INTEGER: BIT POINTER WITHIN IBAY INDICATING BIT AFTER WHICH TO START UNPACKING CNVNULL - LOGICAL: .TRUE. IF NULL CHARACTERS SHOULD BE CONVERTED TO BLANKS

OUTPUT ARGUMENT LIST: CHR - CHARACTER*(*): UNPACKED CHARACTER STRING OF LENGTH NCHR IBIT - INTEGER: BIT POINTER WITHIN IBAY INDICATING LAST BIT THAT WAS UNPACKED
