This subroutine determines whether a specified Table B mnemonic references another Table B mnemonic within the same data subset via an internal bitmap, and if so returns the referenced mnemonic and its location within the subset.
[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

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).
