Thank you for this. I somehow never heard of this. I thoroughly enjoyed reading that and the loss of sanity it resulted in,

"PLEASE COME FROM" is one of the eldritch horrors of software development.

(It's a "reverse goto". As in, it hijacks control flow from anywhere else in the program behind your unsuspecting back who stupidly thought that when one line followed another with no visible control flow, naturally the program would proceed from one line to the next, not randomly move to a completely different part of the program... Such naivety)

The most enigmatic control flow statements in INTERCAL, however, remain PLEASE GIVE UP and DO ABSTAIN FROM – a most exalted celebration of pure logic and immaculate reason.
