FABGXDR is the I/O module called by user-written programs to retrieve the extracted data from an OS sequential file.

It also generates an audit control report detailing the number of segments read from each input DD file. FABGXDR has two processing modes:
- The single-file mode allows FABGXDR to operate using function calls (INIT, GET, EOJ) and JCL compatible with previous releases.
- The multi-file processing mode allows up to nine input files to be read concurrently. This mode requires function codes with a numeric suffix in the fourth character (INIx, GETx, EOJx). The numeric suffix must correspond to an XDRDATAx DD statement where x = {1,2,3,...9}. Each input DD can contain data from a different database and can contain SORT-type, non-SORT-type, or Extract format records.
