Using function in program

[Tim Wessman]

I will show 3 versions. All of them will behave identically.

Code:

Func3(a,b)
begin
local c;
c := a + b;
return c;
end;

Code:

Func3(a,b)
begin
local c;
c := a + b;
end;

Code:

Func3(a,b)
begin
a + b;
end;

Note that the reason these all behave the same is that there is *always* an implicit return on the last item in the runstream of the program. A function must return a single result. That result might not be used for anything, but it must return at least one thing.
