BASIC Loop on a VAX
Back in approx 1990 I was introduced to the University's VAX.
It had a BASIC (interpreter?) so using my Commodore 64 skills (& a colleagues terminal of course) I duly fired up the classic
10 Print "F*ck Off"
20 GOTO 10
I then started laughing as it filled the screen with expletives.
My poor unfortunate colleague had to ask the supervisor how to kill it.
The Supervisor tried CTRL-C, CTRL-Z etc but to no avail.
It turn out that the VAX would print to screen very slowly but would happily run lots of instructions so despite the program being killed it had a massive spool full of swear words ready to send to the screen.
Happy days.
