We still develop application in Ingres ABF.
We use a tool which front-ends SCCS to provide version control of all of our OSQ and also the ABF frames.
We are currently migrating to Sun Solaris, and are unable to port the tool. (I/Code manager.) Currently we are left with pure SCCS which is a real pain.
What do other people use for source control under ABF?
I am aware that Open Road has its own source control built in, but ABF does not contain this feature.
