First, your function name should have () at the end.
Second, the value after 'endfunction' is the return value. In your case, your function will return the value of the variable labeled 'money'.
Third, to call your function just write the function name in your code.

Example:

Hi!

Is there a way to use function to return more than 1 variable ? I'm thinking of returning the coordinates in 3D space, so.. Is it possible with just 1 function or do i have to use array or such to return the values ?

something like
function new_pos(objectn as integer)
x1 = rnd(200)
y1 = rnd(200)
z1 = rnd(200)
endfunction x1,y1,z1

(??)

hmmmh.. that didn't compile

No, you can only return one variable from a function. You would have to either make x1, y1 and z1 global variables or make an array to hold the values.

You could also use a subroutine (procedure) instead of using a function.
