I made quick effort to try to simulate gosub with goto, and noticed that jumping back inside loops is not possible (as the documentation says...).
I understand that when it's For ... Next, but shouldn't that be possible
with Do ... Loop Until x?
Anyway, I'm not sure my simulation does accurately compare speed of Sub to
Gosub... if it does,
then gosub would be 2 to 3 times faster.
Jussi
PS. Try to change last line "End" to "EndEnd" and then try to compile!
