Function/Subroutine Documentation

◆ gettagre()

recursive subroutine gettagre (   LUNIT,
character*(*)  TAGI,
  NTAGI,
character*(*)  TAGRE,
  NTAGRE,
  IRET 
)

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.

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).
