Should I have 13 seperate Macros or one long Sub/Macro??

I was wondering if I can get some opinions on this subject. The reason is
because I have a Workbook that has a Macro/Sub that has 600 lines of code in
it. But here's the thing... The code I have performs like 13 different
routines that could be broken out seperately.

Your opinions are most certainly valuable to me so please enlighten me.


Thanks Tons.
