I started programming in APL in 1980. I programmed in it for about five years. I have a lot of fond memories. I hadn't been too interested in APL for a long time because it was controlled by vendors who could go out of business at a moments notice. I couldn't base anything on it - until now!
I am currently running on Linux. I installed GNU APL 1.3 without any problems. Seems to work so far. Very nice!
I happen to have an APL keyboard that also seems to work fine.
I have some questions that I would appreciate if you can answer as follows:
1. Is there a mailing list for the public to interact regarding GNU APL? (If not, it would be very nice!)
2. I started out using component file. I later moved on to keyed files (from TSR). I never really used shared variables. Does GNU APL have component and/or keyed files? This is pretty critical. If not, is one planned?
3. I wrote the following in portable APL. I think I still have the code. Is there any interest in it?
A. Multi-user keyed file system on top of a component file system.
B. APL code editor
C. Advanced formatter that includes things like commas in numbers, floating dollar signs, parens around negative numbers, fixed decimal places, etc.
D. A large set of various functions that make building applications in APL much simpler. Many are clean-room implementation of TSR's old libraries including user IO with error checking, calendar/Julian date routines, and many more.
