Result
Inside Methods with a return value, the result expression can be used to refer to the result that the method will return upon completion.
result acts like a variable of the same type as the method's return type, and will be initialized to that type's default value (nil for reference types, and 0 or the equivalent for value types) as the method starts. result can be both assigned to and read from.
method Test: Integer;
begin
result := 15;
...
if result > 30 then
...
...
end;
