Most System V code has SCCS tags, but only selec= t bits of System III seem to have them. Where they do exist, often times th= ey're either carried through to the System V file verbatim or=E2=80=8B ther= e's some monkeying with the numbers I can't quite explain but I have some h= unches. In any case, many of the files unmodified between III and V are lis= ted as SCCS version 1.1 in V. I'm not sure there what the significance of t= he version numbers was, and in analyzing several versions, i haven't been a= ble to identify a singular pattern. One pattern I did notice sporadically w= as when comparing SVR1 Release 1 (PDP-11) and SVR1 Release 2 (M68K), all of= these SCCS identifiers I checked roll from whatever 1.x they were in the f= ormer to 2.1 in the latter, presumably the major number being the System V = release and minor being revisions since that was tagged? All speculation th= ough. [snip] Someone else will have to indicate if raw SCCS was used during the time frame for the code you are looking at or if there was some management system built on SCCS that was actually used. What I mean by this is that there was a source code control management system used at AT&T and later Lucent called Sublime (it was more or less mandated at CB at least for the software groups I know of and I am pretty sure I remember it in other locations too). Sublime was used in the '90s onward and likely quite a bit before that time. This system was a layer on top of SCCS, which wasn't allowed to be used directly for source code control. It was true that SCCS tags ended up in your code (usually), but you could not directly use the tag information in any meaningful manor. Sublime used the tag information in it own way that was opaque to the software developers. --=20 Brad Spencer - brad@anduin.eldar.org - KC8VKS - http://anduin.eldar.org
