Function/Subroutine Documentation

nemspecs()

subroutine nemspecs	(		LUNIT,
		character*(*)	NEMO,
			NNEMO,
			NSCL,
			NREF,
			NBTS,
			IRET
	)

Given a Table B mnemonic defined within a data subset, this subroutine returns the scale factor, reference value and bit width of a specified occurrence of that mnemonic within the overall data subset definition, counting from the beginning of the subset.

The values returned include the application of any Table C operators (e.g. 2-01-YYY, 2-02-YYY, 2-03-YYY, 2-07-YYY, 2-08-YYY) which may be in effect for the specified occurrence of the mnemonic.

Parameters

[in]	LUNIT	– integer: Fortran logical unit number for BUFR file
[in]	NEMO	– character*(*): Table B mnemonic
[in]	NNEMO	– integer: Ordinal occurrence of NEMO for which information is to be returned, counting from the beginning of the overall subset definition
[out]	NSCL	– integer: Scale factor in effect for (NNEMO)th occurrence of NEMO
[out]	NREF	– integer: Reference value in effect for (NNEMO)th occurrence of NEMO
[out]	NBTS	– integer: Bit width in effect for (NNEMO)th occurrence of NEMO
[out]	IRET	– integer: return code 0 = normal return -1 = NEMO could not be found, or some other error occurred

A data subset must already be in scope within the BUFRLIB internal arrays for LUNIT, either via a previous call to one of the subset-reading subroutines (when reading BUFR data subsets) or via a previous call to one of the message-writing subroutines (when writing BUFR data subsets).
