This is J Version 6.2 for the Atari ST.
It was compiled using GCC version 2.3.3, and the MiNT libraries version
0.26, and seems to run quite happily under either TOS or MiNT. (I
usually run it under MiNT in its own window under TOSWIN 1.2 (or is it
1.4? It doesn't say...)
I've compiled in the EDITLINE package, a somewhat simplified version of
the GNU Readline system that allows you to use the "standard" Emacs
control keys to edit past commands and present them as new ones. There
is some sort of screen imperfection in this, particularly relating to
the prompt. However, it does work, and makes it much easier to repeat
old commands (TOSWIN also allows cut & paste, which is nice too!)
I've included the readme file from the Editline package, and copies of
the files that I had to modify to get it all working.
There is one notable "bug/feature/hack": The "normal" way that one
exits J is using the "End of File" also known as "Control-D."
Unfortunately, EDITLINE uses Control-D to delete characters. Conflict.
(And a conflict that required a couple of re-boots before it was fixed.)
What I have done is to add the classical ")OFF" command of APL; I test
for a line containing (ONLY) the string ")off" or ")OFF", and change it
to a "\004" (or Control D). It's not standard J, but it does work.
Depending on a job offer that may come next week, I may be moving to
Toronto, which will certainly change my email address. I'll leave two
that will likely get at me:
cbbrowne@csi.uottawa.ca
aa454@freenet.carleton.ca
A reasonable permanent address is:
1000 Stormont St.
Ottawa, Ont.
K2C 0M9
(613)-225-3689
Hope this port is helpful. The next step is to figure out how to use
LINKJ, and stick in some of my numerical analysis code...
