There are 3 types of functions in SB:
1: FUNCTION [arguments]
2: FUNCTION [arguments] OUT [returns]
3: return = FUNCTION( [arguments] )
But actually, 2 and 3 are the same! (this is well known)
X=EXAMPLE(7) can be written as EXAMPLE 7 OUT X
Ok, so there are two types:
1: FUNCTION [arguments]
2: FUNCTION [arguments] OUT [returns]
But wait!
EXAMPLE 7 can be written as EXAMPLE 7 OUT!
so there's only one type cool
