Incorporating the changes, what SCCS calls deltas, into your file
produces a new version of your source code. You do this by issuing
the delta command with the name of the SCCS file. Then SCCS
gives you the chance to describe this version of the code:
$ ls We have editable version of whet.f. Makefile p.whet.f s.whet.f whet.f $ delta s.whet.f Save the changes. Type comments, terminated with End of File character or blank line. Added new timing print out. Our comments. Terminate comments with a blank line. 1.2 This is version 1.2. 2 inserted Statistics 0 deleted No lines deleted 193 unchanged $ ls Makefile s.whet.f Editable and p files have been removed.
