Nice example but doesn't really help a bit more plain text would be better

Can you answer why @foo1 doesn't contain 666 and 123?

In your original question you say the array final1 and final2 are declared as global but i can only print them in there function. the print @final1 just below that and the print at the end do not work..... .

• "It doesn't work" is not a very good explanation (some would say it is not an explanation at all) (How (Not) To Ask A Question)
• my snippet demonstrates why @final1 and @final2 don't contain what you expect. @foo1 = 123; is not the same as push @foo1, 123;

what is a think-o?

Its a brain fart (dict thinko)
