Do you know of languages like C, C++, Pascal, and Visual Basic? They all allow
this. I would even say that one of the few reasons to ever use goto is to jump
out of a deeply nested control structure.

Compiled languages don't have their programs keep track of loops on a stack
at runtime, so there is no problem with using goto this way. And as far as I
know they are much more popular than interpreted languages like TI Basic..
