Parameters

[in]	LUNIT	– integer: Fortran logical unit number for BUFR file
[in]	TAGI	– character*(*): Table B mnemonic
[in]	NTAGI	– integer: Ordinal occurrence of TAGI for which TAGRE is to be returned, counting from the beginning of the overall subset definition
[out]	TAGRE	– character*(*): Table B mnemonic referenced by TAGI via an internal bitmap
[out]	NTAGRE	– integer: Ordinal occurrence of TAGRE referenced by (NTAGI)th occurrence of TAGI, counting from the beginning of the overall subset definition
[out]	IRET	– integer: return code 0 = normal return -1 = TAGRE 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).
