>I am working with several dozen applications, written in all flavors of Fox, from DOS version 2.0 to Windows 2.6 to Visual FoxPro 5.0. Is there a version control software that can be used on all versions? My choices at present are PVCS and Visual SourceSafe.

>In addition, will SourceSafe work with non-Microsoft products? We have several other projects written in PowerBuilder, Clipper, Delphi, Paradox, and BTrieve. We are trying to standarize on one version control package for the lot of them.

I am currently using VSS 5 for all my projects -- VFP, FoxPro 2.x and other languages as well. VSS works great with all of them. The only difference to note is that I have VSS integrated into my VFP projects so I can do VSS functions within the Project Manager. Everything else, I use the VSS Explorer to Check Out, Check In etc.
