Without cheating (using a 0.01 second wait, or having a trigger trigger itself at the end of execution, or anything else that is slopy and could lead to bugs...
Is there any "onUpdate" or "onStep" type event that I can register an event with in Galaxy script?

Also, if anyone has a good listing for the Galaxy API I'd love it

Tks ahead of time.

Would help if I knew exactly why you needed such an event, there may be a better solution (such as running a trigger whenever you would trigger an update). If you want a continuous evaluation of a condition then you will need a periodic trigger, there really is no other way of doing it.

Also recursive triggers are a valid way of doing certain things.

Heh, I asked exactly what I needed to know...
I don't have a specific need for the onStep function, I just was digging around the API to get a feel for it... most APIs have some form of update function you can attach continuous logic checks to... I know there's a nice event handler to manage all of that jazz, and I know 95% of the time, you should use that, but I was just curious.

Primarily, I'll try to write as much as I can in GS and not have to use the GUI triggers as they tend to be a tad (relative) slow, and I just like working in code better, I'm a control nut (I'd rather know how things are being done, not just what they are doing).

You would have to do that manually running triggers at the end of some functions like you said, I guess.
