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?

The workspace (.BXWA from ~30000 to ~60000 bytes). It also contains a character set for
Vt220 for the APL character set.

INS APL6.TSK/INC=37000 to max the workspace for the single precision version.

[370,360] on the RL02 disk. I remember having this work back in the mid-1980s butI have
not been able to get it to work today. If I link it with ODT it seems to blow up when the
first overlay is loaded. If anyone could help with that I?d really appreciate it!
I remember we had APL at Rose-Hulman when I was in college there from 1978-1983.? At
first I thought it was on the VAX-11/780 that showed up over the summer of 1980, but now I
realize it had to have been on our PDP-11/70 running RSTS/E. Probably APL-11 V1.X since it
was there in the Fall of 1978 when I started.? We had a couple of DEC LA36's with the
APL character set and keyboards.

? On page 1-5 of the APL-11 Reference Manual that Mark posted there is a table showing
the ACII equivalents for the special APL character set.? There are also instructions there
on how to do it.? It's a combination of characters and backspaces.? Kinda tough on a
video terminal but workable on a printer.
