Macros in Excel

[jong2k4]

I've been studying up on some of the advanced functionality of Excel using the Excel help files... I've come across macros, and they appear to be important, but there is very little info in the files regarding how to create and use them. I know they are written in Visual Basic, and I have some limited knowledge of that, but that's about the extent of my knowledge.

Would someone enlighten me?

(I plan to study up on Excel a lot this summer, and if anyone else would like to do the same we could trade how-to info and suggestions on implementation. I'm focusing on accounting applications for now, and will probably focus on organizing/presenting laboratory data later on.)
