I have several primitive VB functions that I used in several Macros. I have been cutting and pasting to include them in the larger macros with much border functions. As time has gone on and numbers have increased any changes to either primitive or broad function requires a lot of rework. Is there any way to automatically include functions from library? Then it seems that updating would only be a compile away. Or could they somehow be included as DLLs.

See #Expand in the docs.
