I believe this is the intent of the until command. It’s like a next except that when a jump occurs to a previous line number for the loop, it will continue until exiting the loop.
unt(il)
Continue execution until the line with a number greater than the current
one is reached or until the current frame returns
In general, to “step out” of the current function, use return.
r(eturn)
Continue execution until the current function returns.
