Intro to Functions

In this tutorial you will learn how to ...
~ Create/call simple functions

Ok seeing as how this tutorial is really short I will show you our final product and explain it from there. (this is a modification of our old program that counts up to a certain number)

Global x=0
Global st=0
While st=0:
add()
printx()
stopx()
Wend

Function add()
x=x+1
End Function


Function printx()
Print x
End Function

Function stopx()
If x>1000 Then st=st+1
End Function 
 

Ok first you will notice that x and st have global in front of them, this allows both of those variables to be called in functions (an example of globals would be life or experience), ok now lets skip down to

Function add()
x=x+1
End Function

function is how you start your function followed by its name "add" (you may name it what you want) followed by an open/close parenthesis (these are for parameters but we wont get into that now) then at the end of the function it is closed with end function.
Now you will notice that we have replaced our loop with this

While st=0:
add()
printx()
stopx()
Wend

this is because we need to call up the function so now the program will run through each function and repeat it, (please note that in this case functions were really impractical but this was just an example, functions will be needed later when we get into graphics).
