[apluslist] A+ on Tiger (OSX 10.4)?

[G.Mark Stewart]

Has anyone gotten A+ to compile and work on OSX 10.4?

I've used quite a bit of APL, but a long time ago, and
  am completely new to this list.

Is there any advantage to using emacs over the terminal
window on my machine? Or in using X11 over any of the
others?

I'd like to do some crunching of fairly large Unix files. Are
there any fixed limitations to the size of files that can be
read in as data in A+?

Thx!

Mark
