I always check diagram version from Project>HELP>About
I don't know the command which shows the diagram version.
Hello.
Also you can call from command window the form Include.
SHOW !!CDCINCLUDE
And this form helps to include branches from one scplin to other.
for version : try q bann
Without entering project also we can see the version.
after running batch project window will open, on top right of window ? - X exists. ? will show the version
