So, other than being "non main stream" and even "obsessively weird", is there any *technical* reason to maintain sequence numbers?
I think this is another "religious" issue not worth fighting over. Some programs are maintained with strict sequence numbers, and a utility such as IEBUPDTE or IEBUPDTX is used to maintain changes. (Does anyone still use IEBUPDAT?). There are some reasons for this use, such as maintenance of commercial software, but even that is declining. Some programs maintain sequence numbers, but with frequent alteration (RENUM, etc.). These I rely upon heavily. For one, they make it easier to disambiguate roughly similar code sequences (more prevalent in assembler?). More importantly, they make it trivially simple to edit code after reading a virtual or physical program listing (Locating by line number rather than search). Gerhard Postpischil Bradford, Vermont
