[commandos]

Hey,

I took computer science a couple of years ago in high school and now im trying to remember some of the things we learned. just wondering what the difference is between a function and procedure and when to either. thanks in advance

procedure: carry out a set of common commands
function: return a value

One thing I want to point out, a procedure is a function, except it doesn't return anything useful, Ie void which is nothing.

Bla Saad beat me to what I was just about to say :p

Procedures are void functions. The simply execute code when requested without returning any values.

thanks all

I thought it was a legimate argument and may be helpful.
