Since it is a development fix, the original backup files will be kept. That is, rev 5 will overwrite rev 4, preserving the initial backup. While we're talking about LFIX: I am storing LFIX 1.4 which avoids the "PROGRAM INTERRUPT IN NON-PASCAL PROGRAM" under CMS 4 and 5. It seems CMS is not able to run a relocatable MODULE under CMS 4 or 5 unless it has been NUXCLOADed, which 1.3 did not do. Eric
