What is the difference between functions and procedures?

Answer 1

This is a good question, and I some what consider them the same thing BUT.... A function is a separate functioning procedure that is summoned/invoked with or without parameters in order to carry out a task or "procedure" defined by the developer.
The procedure depends on the circumstance really, I must say I got a little confused lool because it's simple but tricky at the same time.

Answer 2

A procedure is just a special case of a function, when it doesn't return value...
