Functions.

[Nocturnal]

What is a function, how do you pass something to a function? Can anyone
elaborate on this for me? I'm rather new to programming.

 

[OpticTygre]

A subroutine and a function are practically the same thing. The only
difference is that a function returns something.

Example:

Public Sub AddNumbersSubroutine(x as integer, y as integer)

Debug.WriteLine(x + y)

End Sub

Public Function AddNumbersFunction(x as integer, y as integer) as integer

Return x + y

End Function

Then, in another part of your program, you can either say:

Call AddNumbersSubroutine(10, 32)

Or, you can say:

Dim myValue as Integer
myValue = AddNumbersFunction(10, 32)

Hope this helps.

How do you know what to type between the ()? That is what perplexes the
crap out of me. I get confused. It's like ok say you have function()...
would you just type whatever the function may have in between the ()? Like
function(return_this)?

Optic,

That helped me tremendously. I didn't realize that you were going to USE
them later on in the program.
