AHK Scripts Question

[MATT238]

I'm new to scripts and have just recently started using them. I've downloaded Roland's Functions and am using a script that cascades, closes lobbies, and auto-registers. I've found other scripts I'd like to try....Can these all be combined into one file or do I need to save each script seperately and then load them individually when I want to use them? Will I have conflicts running too many scripts at once?
