Thank you for replying.
In MUMPS, all globals and routines are saved within the system. There are no separate files for us to open, for example, in a notepad++. Unless we manually export each and every routine through Workstation.
What I need is: when a colleague makes a change to a "Window" or routine, I have control, and know which row that colleague made the change. And that the "commit" is done only with the routine or window changed, and not the whole system. And if something goes wrong, I can go back to the previous version, via SVN or GIT. In TORTOISE SVN for example, in other languages like C#, I can see what each user has changed in each line of code, including the date. I want to do the same with MUMPS, but I don't know how to do it.
I thank you for your attention.
