IIRC, Pascal (the CDC Pascal I used in the 70s and 80s), allowed gotos to any label in scope. In the main program, one could declare a label (mine was an emergency 666:) and then goto that label from any procedure or function inside the main program. I used that for emergency exits, when I ran out of storage or some such thing. Ada exceptions eliminated that goto need. I don't know about modern Pascal. -- Bob Collins
