There is no easy version control for SC.
See this thread: www.scriptcase.net/forum/showthread.php?9291-Subversion-source-code-version-control .
In the thread is given a way that one can backup and revert to an earlier version of ones projects, which is good if something drastic happens to ones ScriptCase projects.
In a different scenario one may wish to go back to an earlier version of a single application within a project. This may for example be if one is exploring several ways of designing the application in the development phase. In this case one might have a basis version of an application, make a copy and change that. Then go back to the basis version and make another copy to work on, etc. However, I don’t find any way to make a copy of an application in the SC IDE.
Perhaps there is another easy way to make a copy that I just haven’t seen as a new user?
