Tracking versions with SCCS

Concurrent edits of same SID

Under normal conditions, more than one get -e for the same SID is not permitted. That is, delta must be executed before a subsequent get -e is executed on the same SID.

Multiple concurrent edits are allowed if the j flag is set in the SCCS file. Thus:

   $ get -e s.abc
   1.1
   new delta 1.2
   5 lines

may be immediately followed by

   $ get -e s.abc
   1.1
   new delta 1.1.1.1
   5 lines

without an intervening delta. In this case, a delta after the first get will produce delta 1.2 (assuming 1.1 is the most recent trunk delta), and a delta after the second get will produce delta 1.1.1.1.
