Actually fox, i have more complicated structures than that, i have one starting from do with 80 lines and indeting level to 14, and i have no goto's there, not one, but it surely is confusing to run trough it. And for my latest and in my opinion best application, is using goto in a select case based structure (to exit the select case) Can you that in another way too Fox?

Also, Meg, TI83 is my best friend, it's a graphical calculator with inbuilt programming language and can be connected to your pc, and it handles complex values and everything, TI83 is great!
