Does SCCS allow you to "un-delta" a version???

[Bill Irwin]

I am just getting acquainted with the SCCS system commands and
have found that sometimes you can think a modification is
complete and delta it, only to discover later that there are
still some bugs in it.  Is it possible to Get the most current
version back, make some changes, then delta the same version
number again?

Or is the delta step a final one, where further mods have to
produce a new version?
