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

    4/18/2021 IBM leaves apl2?

    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 [10/2015 gone].

    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 1979 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

    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

    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.

    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).

    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 posted to the newsgroup. This used to
    be autoposted, but MIT does not appear to do that anymore.
    An old (2018) version is available at ftp://rtfm.mit.edu/pub/
    (where all the autoposted faq's are archived), in particular ftp://rtfm.mit.edu/pub/usenet-by-group/comp.lang.apl/APL_language_FAQ.
    Another place for (old) faq archives is http://www.faqs.org/faqs/,
    with this faq at http://www.faqs.org/faqs/apl-faq/.

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

    A+ [1/2002]
    A+ (aplus) 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.
    A wiki describing using A+ under Debian, in emacs to get the fonts.
    The BAA has had some success in porting to Windows, see

    APL\11 is a freely available APL interpreter for UNIX (C),
    thanks to Michael Cain. Currently has some bugs.

    APL\3000 [9/7/2010]
    An old (1970s) APL for the HP 3000, similar to IBM APL
    SV. Now partly revived through HP 3000 emulation. Source code
    exists but licensing cloudy (check news group posts).

    APLX (was APL.68000)[8/2016]
    APLX is no longer available from MicroAPL, however Dyalog is
    hosting free downloads of the final (version 5.0) APLX
    installation packages and documentation

    APLSE/LRNAPLSE (APL*PLUS v10 freeware, PCDOS, W95/98, NT, runs
    under DOSBox, Android):

    APLSE is a version of Manugistics/STSC's PC APL, available
    with very little documentation. It can be found at
    http://www.dosbox.com/DOSBox, a DOS emulator for Windows, Linux, and FreeBSD
    It is available for Android by GEMESYS at https://play.google.com/store/apps/details?id=org.gemesys.android.aplse
    LRNAPLSE is a package
    including APLSE, on-screen lessons (with additional
    documentation), and the APL*PLUS Demo (more documentation).

    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
    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
    Try to use this method in Windows ME - it might be the way out.

    been taken over by APL2000 (above).

    a hybrid language combining a functional array language based on
    Trenchard More's mathematical treatment of nested arrays
    called Array Theory, with a procedural language with familiar
    control structures. Q'Nial is open source, with versions available
    for Unix and Windows.

    A: Besides commercial products that come with the interpreters, there are:

    o Fonts for TeX, laTeX, the X windows system, postscript, and
    truetype (windows) are available. See http://www.math.uwaterloo.ca/apl_archives/apl/fonts[dead]

    o Truetype fonts for windows are available from ISI.

    o Dyalog fonts are Adrian Smith's APL385 (and APL333) fonts, free
    download at http://www.dyalog.com/apl-font-keyboard.htm

    o Truetype fonts: Dyalog APL and Vector APL are available gratis, if
    you send a blank, formatted disk:

    (See his article in the April 1993 issue of VECTOR journal)

    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.

    o Paul Houle has made a DOS window font file suitable for use with
    old STSC APL's available here [5/17/04]:

    o Paul L Jackson's pljtools.zip contains DOSAPP.FON which if put in
    the Windows\Font directory, will provide an 8x16 APL font for a DOS
    window. This should work for various MS Windows products and
    APLSE. This is available at waterloo
    http://www.sigapl.org/Archives/waterloo_archive/apl/apl-plus/index.html[12/2020] and

    o A variety of fonts and tools is available from Vector:

    o Emacs can display APL fonts, see

    o Unicode fonts such as https://www.gnu.org/software/freefont/ can display APL glyphs
