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

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? What
    about APL keyboards/stickers?
3.  Can I compile APL?
4.  What tools exist for APL?
5.  Can I get an APL font for X?
6.  What information exists online about APL?
7.  How do I get book Y?
8.  What good APL books exist?
9.  What user groups exist?
10. What's the latest  APL conference?
11. How do I pass APL functions from one APL to another?
12. How do I write APL using only ASCII?
13. Where can I find APL employment information?

7. SIGAPL Software Library
New Name, New Addresses:
SIGAPL has made major changes in its software distribution system.
The SIGAPL Software Library replaces what was formerly known as
the "Software Exchange."  SIGAPL wants to make array processing
software much more widely available and easy to get.  We want it
to be decoupled from annual APL conferences, available year-round,
unbundled by interpreter, and electronically free.  Thanks to Lee
{*filter*}ey at the University of Waterloo, this software is now
available at:

  - ftp://archive.uwaterloo.ca/languages/apl/software-library

  - ftp://wuvieai.wu-wei.ac/pub/lang/apl (Vienna mirror of Waterloo)

It's also available at:

  - BBS\APL: (see above, FileArea APL96)

APL96 Conference Software Highlights:
-  MERLIN   : Two new AWS mind bogglers (Langlet, FR)
-  GRAN     : AWS []G Graphics (Buzin, RU)
-  NFILES   : W3 Long file names, National Characters (Glantz, SE)
-  APL2OS2T : APL2/2 Tutorial for OS/2 (Jizba, US)
-  APLSE    : Free APL*PLUS v10 Interpreter (Manugistics/APL2000)
-  LRNAPLSE : APLSE Tutorial & Documentation (Holt, US)
-  UNLOCK-D : Unlock locked fns in any small AWS (Holt, US)
-  SL-Guide : How to add to the SIGAPL Software Library

SIGAPL Software Guidelines:
The SIGAPL Software Library (SL) is the premier venue for APL,
J, and other array-oriented authors to display their programming
ideas and skills, and for vendors to showcase their demos and
products.  APL and J software authors and vendors are invited
to send their material on a 3.5" DOS disk to:

  Lee{*filter*}ey, Mathematics Department
  University of Waterloo
  Waterloo  Ontario
  Canada    2NL 3G1

Tell him that it's for the Software Library.  You may send your
software at *any* time of the year.  FTP upload is not currently
available, but is expected to be operational by 1997.

SIGAPL's updated Software Library guidelines are:

- Include an ASCII file (call it WSNAME.TXT) to describe what
  the software does, and what hardware and software is needed to
  use it.  English is preferred, and other languages are welcome.

- Think electronically.  Your software needs to be packaged as a
  stand-alone product for electronic distribution.  Good documen-
  tation adds real value to your software.

- Put all of your material in one single .ZIP file for easy FTPing.

- Include any needed copyright permissions.  Copyrighted software
  can't be distributed without permission.

- If possible, provide APL software in both its original form and
  as an APLACSCII file.  APLASCII software (v1.4) is available for
  all major APLs at the electronic sources listed above.

- Check your software for viruses.  Archive.waterloo.ca will also
  check your software for viruses.

- Authors should pay special attention to the quality, usefulness,
  and documentation of their work, and should include their name
  and address (including email).

- Significant improvements and major updates of prior SL software
  are welcome.

Things Take Time
The transition to an all-electronic system will not happen instan-
taneously.  For the next year or so:

- Mail-order service is available for those without good telecommun-
  ications.  For a post-paid disk copy of the APL96 edition of the
  Software Library, send $US6 (or $US6 equivalent in a bank check in
  any hard currency) to{*filter*} Holt, 3802 N. Richmond St.  Arlington
  VA 22207 USA.

- The SIGAPL Software Library will continue to be available on-disk,
  on a limited basis, at future APL annual conferences.

- Logistic problems will surely occur.

Send comments, feedback, and suggestions about these changes to{*filter*}

(10) Conferences

APL97 - Share Knowledge/Share Success - August 17-20 - Toronto

Fellow APL and J Enthusiasts - Welcome Back to Toronto!

The Toronto APL Special Interest Group, local host of the highly
successful APL93, is pleased to again take up the challenge of hosting
this annual event for 1997. Please mark your calendar now for this
comprehensive three day forum in downtown Toronto.

Continuing the standard of excellence set by the 1996 J User
Conference and the APL96 conference, APL97 will consist of
presentations by invited industry-leading speakers, APL and J product
vendor forums, interactive tutorials, and hands-on workshops in
PC-equipped teaching labs.

The Toronto APL SIG looks forward to your support in helping us to
provide the usual high standard of APL conference that we have all
come to expect.  Please join us in the spirit of community and
cooperation that has been the hallmark of this dynamic and highly
focused global family.

The Share Knowledge Share Success theme has been chosen to celebrate
APL and J. This year's conference will focus on providing tutorials
and "hands-on" sessions in computer laboratory facilities. Experts and
fellow-users will share their knowledge to help assure your success!

Please refer to the APL97 Website:


for complete and up-to-date conference information, including
conference schedule and program, registration details, and
accomodation info.

Cost and Location

The conference will be held in downtown Toronto, at Ryerson
Polytechnic University, which features modern, well-equipped computer
lab and lecture room facilities, an adjacent student-operated hotel,
and dining facilities.

Registration price for the conference has been set at a very
reasonable $160 CDN ($115 US), with an optional evening dinner event,
a dinner cruise on Lake Ontario, for an additional $40 per
person. Registration can be by mail, fax, or through the website.

(11) Migration of applications

Different APL vendors store workspaces in completely different
formats. This has greatly reduced sharing of functions among users,
and made it difficult for users to migrate between vendors and even
between machines. Here there are two main options -

   1. Use the Workspace Interchange Standard (WSIS), documented in the
      ISO standard. This has been partially implemented by various
      vendors. For example Manugistics (STSC) uses an SLT workspace to
      do the reading/writing.

   2. Use the IBM )in and )out .atf files (documentation?)  Here are
      some concrete instructions, courtesy of Eke van Batenburg,

      You only port <APL>, no GUI, no file I/O, no graphics, no locked
      objects. The following recipees use (arbitrary choosen) filename
      TRANSW.ATF on floppy as intermediate. "<>" means "next line".
      1 Macintosh APL68000 export to floppy:
        []MOUNT'Untitled'  <> )OUT 0 TRANSWS
        In finder, change file name to "TRANSWS.ATF"
      2 Macintosh APL68000 import from floppy:
        In finder, change file name to "TRANSWS" (without ".ATF"
        extension!!!)  []MOUNT'Untitled' <> )IN 0 TRANSWS Problems:
        "INVALID FILE" can mean "SYMBOL TABLE FULL" (check ")SYMBOLS"
        and increase them) to 1000) or comment lines in file (remove
        all lines beginning with "*" using any editor and try again).
      3 Atari APL68000 export to floppy:
        []MOUNT 'A:' <>  )OUT 0 TRANSWS
      4 Atari APL68000 import from floppy
        []MOUNT 'A:' <>  )IN 0 TRANSWS
        Problems: same as in point 2.
      5 IBM APL2/PC export to floppy:
        )HOST A: <>  )OUT TRANSWS
      6 IBM APL2/PC import from floppy:
        )HOST A: <>  )IN TRANSWS
        Problems: none experienced upto now
      7 IBM mainframe export to floppy:
        start APL with "APL2 CASE(2)" (necessary for underscored
        conversion) )CLEAR <> )COPY workspacetobeported (NOT LOAD!!!!)
        )OUT TRANSWS <> )CLEAR <> )IN TRANSWS <> )OUT TRANSWS (yes, 2x
        seems to work, 1x sometimes gives gibberish, I don't know why)
        Download ....APLTF.TRANSWS to floppy, rename to TRANSWS.ATF
        Problems: if you download with Kermit: set TEXTMODE OFF and
        set file TYPE BINARY
      8 IBM mainframe import from floppy
        I have no experience with this, but I suppose:
        Upload TRANSWS.ATF to file ...APLTF.TRANSWS
        )IN TRANSWS
      9 APL2000 APL+DOS, APL+UNIX, APL+Win export to floppy:
     10 APL2000 APL+DOS, APL+UNIX, APL+Win import from floppy:
        Problems: Different from IBM or APL68000 or "extended standard"
        are: "A B C[2]" is B, partioned enclose, squeezed quad,
        monadic ",[1.5]", take with axis and scalar functions with axis.
     11 Dyalog APL:
        im/export functions have since several years a bug that thinks
        that your recordsize is wrong. If you manage to correct only
        this, it seems to work find.
     12 Contribution of others to TRYAPL(?), IPSharp APL, ISIAPL etc.

    3. Write the functions/data out to ASCII files using some sort of
      transliteration scheme (see 11). This has the advantage over
      (1) that the files are human-readable and editable.

All schemes suffer from the basic incompatibility between APL
vendors. This comes from extensions to standard ISO APL in several

   1. Different built in functions - the quad functions. This includes
      file IO, graphics etc. Also the (mostly obsolete) ibeam
   2. Generalized arrays - boxes versus nests. A major fight in the
      community for at least the last 10 years. Unresolved.
   3. User defined operators - not all implementations allow this.
   4. Multivalent functions - not all implementations allow this.

Each instance of the above requires someone who knows both
implementations to rewrite the code. Hence only ISO APL is easily

(12) Writing APL in ASCII

Almost all vendors have provided ways to enter APL from non-APL

however, they all used different symbol sets and different
transliterations. Hence all are incompatible. Various users, seeing
the advantage of this approach versus the WSIS have tried their

I there are several separate issues: writing an APL character, writing
APL data, writing APL functions, and writing out a whole workspace.

Approaches for character :

1. My own approach - see symbols3v1.txt on csi.
   Example: s  .is + / .ro , a

   J-ish vertion called APL!
   Example: s  <- +/ ? , a

   Example: s {<-} +/ {rho} , a

Approaches for  objects:

   scheme for this that includes data and functions. See his article
   at APL92. Code for various APLs is available at waterloo. Example:

   Code is also available for incorporation of APL into{*filter*}

2. Jim Weigang proposes the more familiar "Del editor" output
   format. Sample code for this translator is available in this

(13)      Where can I find APL employment information?

The APL Skills Database

a joint project of:

     The Toronto APL Special Interest Group
     The ACM Special Interest Group on APL

Dear APL Employer or Employee:

The Toronto APL Special Interest Group, and the Association
for Computing Machinery Special Interest Group on APL, are
pleased to provide the free worldwide employment information
service known as the APL Skills Database.

Recognizing the niche-market nature of the use of APL in data
processing, the APL Skills Database project was launched in
1994 to aid companies and employers looking for APL-skilled
personnel, and to help APL-skilled professionals seeking
employment opportunities with companies needing APL expertise.
To date, at least six participants in the project have been
successfully placed in APL-related employment positions by
using this service!

How does it work?

The APL Skills Database consists of a section on the website
of the Toronto APL SIG where employers may post employment
information, plus an Email broadcast facility. Employers
are encouraged to simply submit the details of jobs on offer,
and these will be posted at our website. This info, in the
form of monthly job bulletins, will also be broadcast by email
to APL-skilled participants who have subscribed to this service.

How can I get involved?

The APL Skills Database is a free service for both employers
and job-seekers. If you are an employer looking for APL skills,
just send us the details of the position being offered and we
will post them on our website. APL-skilled persons who subscribe
to the APL Skills Database will be sent these incoming job
notices via email as they arrive.

The APL Skills Database will also post resume information
of APL-skilled consultants, contractors and individuals
who may be in the job market. If you already have your own
website, we will link to it from our site.

All information and questions about the project may be
directed to either of our email addresses:

The Toronto APL SIG website is at:   http://www.*-*-*.com/
The ACM SIGAPL website is at:       http://www.*-*-*.com/

The APL Skills Database can only work with the enthusiastic
participation of employers seeking APL skills, and employees
seeking APL employment. Please join us in this unique project.
