APL Frequently Asked Questions (well some, anyway)
Maintained by S.W. Sirlin
Thanks to the many people who have contributed to this list.

2/2010 apl movie blog.


First, what is APL?
APL is the first array processing language (that I know of anyway).
The following was extracted from http://www.acm.org/sigapl/whyapl.htm. (Who's computer is this?)

The language was invented by Kenneth E. Iverson while at Harvard
University. The language, originally titled "Iverson Notation", was
designed to overcome the inherent ambiguities and points of confusion
found when dealing with standard mathematical notation. It was later
described in 1962 in a book simply titled "A Programming Language"
(hence APL). Towards the end of the sixties, largely through the
efforts of IBM, the computer community gained its first exposure to
APL. Iverson received the Turing Award in 1980 for this work.

APL is a user-oriented notation, particularly well suited for
communication from people to other people or to computers. The
notation consists of a set of symbols (letters, numbers, punctuation,
algebra, and special shapes), with a very simple set of rules (syntax)
for putting them together to describe the processing of data. The
data can be either numeric or literal (which includes words and text
handling).

In fact there are about a hundred different "primitive"
(i.e. fundamental to APL) operations which can be performed. This can
be compared to having a calculator with over 100 different function
keys.

Following the old Chinese proverb that a picture is worth a thousand
words, the APL symbol set is the equivalent of many words in
describing algorithms or procedures. Often one or a few APL symbols
(function) can have the same result as several lines of code in
another computer language or of several paragraphs in English.
...See http://www.acm.org/sigapl/whyapl.htm (Who's computer is this?)
for the rest of the article, or check out some of the web links or
books listed below for more information.
Wikipedia has a good overview as well
http://en.wikipedia.org/wiki/APL_(programming_language (Who's computer is this?) ).



The questions I'm answering here are:
1. Where can I find APL for machine X?
2. How do I use APL on an XX terminal connected to machine YY?
3. What about APL keyboards/stickers?
4. Can I compile APL?
5. What tools exist for APL?
6. Can I get an APL font for X?
7. What information exists online about APL?
8. How do I get book Y?
9. What good APL books exist?
10. What user groups exist?
11. What's the latest APL conference?
12. How do I pass APL functions from one APL to another?
13. How do I write APL using only ASCII?
14. What about Unicode?

The primary format for this faq is html. I use lex and aplc to convert
this to a text version that is autoposted to the newsgroup.

(1) Q: Where can I find APL for machine X?
A: APL SOURCES

A+ [1/2002]
A+ is an APL dialect available (as source) under the GNU GPL for
various Unix, including Linux, Solaris, FreeBSD, NetBSD,
developed at Morgan Stanley by Arthur Whitney et al.
http://www.aplusdev.org (Who's computer is this?)
http://sourceforge.net/projects/aplus/ (Who's computer is this?)
The BAA has had some success in porting to Windows, see
http://www.vector.org.uk/aflat (Who's computer is this?)

APL\11
APL\11 is a freely available APL interpreter for UNIX (C),
thanks to Michael Cain. Currently has some bugs.
See also openAPL below. Port to FreeBSD available

Fonts under W95, WNT, (WME?) are troublesome. Here is some
information from Allan Zenth (allan.zenth@tryg.dk):
I tried to use APL-PLUS v.10 (essentially the same as APL SE) under Windows
95 and Windows NT. I don't know about Windows ME.
First the bad things: You cannot work in a window with symbols (only
full-screen) and using a code-page for symbols is not possible in NT.
The difficult thing is to have a stable full-screen situation and the most
difficult was NT.
1) Make a short-cut on the screen to the apl.exe file. Go into the
properties (right-click on the icon).
2) On the program-page refer to the bat-file in the command-line field an
set run to maximized
3) On the memory-page I use 1MB in EMS, XMS& DPMI - perhabs not important
4) On the screen-page set full-screen
5) On the misc-page remove the check-mark for Ctrl+Esc - Important to have
in APL
6) Go into C:\WinNT\Pif and make sure, that you have the same short-cut
here
7) Here should also be a short-cut for your font.com:
7a) On the program page refer to the file itself on the command-line, set
run to maximized and remove the mark in "close on exit" (important!!)
7b) The same alterations on the other pages as above.
8) If you use aplprint.com for function-printout it should be treated as
font.com
Try to use this method in Windows ME - it might be the way out.

o STSC, now Manugistics, used to distribute a rom chip with the APL
characters for use in old monochrome adapters (now almost
extinct). There's also code called SIMCGA.COM, that makes an old
Hercules act like a cga (itself pretty old).

o Fonts from several vendors are available for use (free of charge)
in preparing articles for APL Quote Quad, APL conference
proceedings, or other educational articles. This can be found on
the ACM SIGAPL Web site. Word processing Templates to aid the
author in preparing articles for conference proceedings or for
submission to APL Quote Quad can also be found on the ACM SIGAPL
web site.
