Take advantage of the Versioning tool, a graphical user interface to SCCS, to manipulate files and perform SCCS functions. Even if you don't know SCCS commands, this intuitive method lets you check files in and out, as well as display and move through history branches.
Use the Versioning tool to:
Check in files under SCCS
Check out and lock a version of the file for editing
Retrieve copies of any version of the file from SCCS history
Peruse the branches of an SCCS history file
Back out changes to a checked-out copy
Inquire about the availability of a file for editing
Inquire about differences between selected versions using the Merging tool
Display the version log summarizing executed commands
