I'm currently working on a custom version control implementation.
I'd like to show differences between a copy of a previously saved routine as a merge of the ^ROUTINE Global and the current version of that same routine.
I've found legacy Documentation for %RCMP which does the trick in the terminal but I'd like a similar result stored inside a variable.
I also want to show differences, not only see if they are the same or not.
The management portal has that exact feature, so maybe someone can direct me to the function that is being used there.
