Re: REL APL-11

The only things I remember about APL were: 1. Square divide symbol formed something that looked like a domino (1 over 1) and was the random number generator. 2. Someone always finds a way to do a moderate sized task in one line of code. The ultimate obfuscated code contest. Marc On Mon, Mar

Stupid question time. I last used APL in a class in 1975. Back then you needed a magic terminal and/or a magic Selectric typeball. How does one input or print a program on a PDP-11 with mere mortal equipment? Thanks, Marc Howard On Mon, Mar 30, 2020 at 4:07 PM John H. Reinhardt via cctalk <
