Glb.Match is a read-writable built-in segment attribute that is intended for use in report logic in conjunction with the Match logic command, which compares key values in two extract files. It is set to the name of the extract file that identifies the next extract file to be read. A space value denotes that both files are to be read (because the current key values match). It is a string expression of up to 64 characters.
Note: Glb.Match is always set to a space outside the Match loop. Correspondingly, it is meaningless to reference Glb.Match outside the Match loop.
