I have a huge library of extremely complex code that we run every
night. In general terms, 1/3rd of that code is used only once a day
when the book is created. Another 1/3rd is utility code that could be
removed to some other location. Finally, there is the last third that
needs to stay with the book and the users interact with.

The code is currently located in a 2.8 meg XLA on a network drive.
This is also a problem because the first person that opens the book
"locks" the XLA and I can no-longer save changes to it. Additionally,
if the network falters even for a second, the link to the XLA "goes
bad" and every command starts returning random errors.

So what I'm thinking about doing is moving the code the user touches
into a separate library of some sort, and then saving it directly into
the book. That should eliminate both problems, as well as ensure they
have the right code version for the book they have open.

So finally, here's my question: if I place the code that needs to be
with the book into an XLA, can I copy it into the spreadsheet's
modules via VBA? Are there general-purpose commands for moving code
around in general?
