Function/Subroutine Documentation

subroutine setvalnb	(		LUNIT,
		character*(*)	TAGPV,
			NTAGPV,
		character*(*)	TAGNB,
			NTAGNB,
		real*8	R8VAL,
			IRET
	)

This subroutine can be used to write a data value corresponding to a specific occurrence of a mnemonic within a data subset, based on its position relative to a different mnemonic within the subset.

The subroutine first searches for a specific occurrence of a pivot mnemonic, counting from the beginning of the subset. From there, it then searches in either a forward or backward direction for a specific occurrence of a nearby mnemonic, and if found stores the specified data value in the corresponding location within the subset.

Parameters

[in]	LUNIT	- integer: Fortran logical unit number for BUFR file
[in]	TAGPV	- character*(*): Pivot mnemonic; the subroutine will first search for the (NTAGPV)th occurrence of this mnemonic, counting from the beginning of the overall subset definition
[in]	NTAGPV	- integer: Ordinal occurrence of TAGPV to search for, counting from the beginning of the overall subset definition
[in]	TAGNB	- character*(*): Nearby mnemonic; assuming TAGPV is successfully found, the subroutine will then search nearby for the (NTAGNB)th occurrence of TAGNB and store R8VAL as the corresponding value
[in]	NTAGNB	- integer: Ordinal occurrence of TAGNB to search for, counting from the location of TAGPV within the overall subset definition. If NTAGNB is positive, the subroutine will search in a forward direction from the location of TAGPV; otherwise, if NTAGNB is negative, it will instead search in a backwards direction from the location of TAGPV.
[in]	R8VAL	- real*8: Value to be stored corresponding to (NTAGNB)th occurrence of TAGNB within the subset
[out]	IRET	- integer: return code 0 = R8VAL was successfully stored -1 = the (NTAGNB)th occurence of mnemonic TAGNB could not be found, or some other error occurred

Before calling this subroutine, a BUFR message should already be opened and initialized for output via a previous call to one of the BUFRLIB message-writing subroutines.
