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?

(10) Conferences

  APL96: Designing the Future
  July 28, 1996 through August 1, 1996
  University of Lancaster, UK
  Sponsored by ACM/SIGAPL

  Invitation and Call for Participation (abridged)

  ACM/SIGAPL (The Special Interest Group on APL) is pleased to
  announce the convening of the 1996 International Conference on APL.
  The theme of the conference is Designing the Future.  This year, the
  focus will be on tools, techniques, technologies, and applications
  that bring APL to the leading edge of computer technology.

  The APL96 Program Committee seeks papers that showcase the place of
  array programming languages in the technological tools available for
  research, development, design, and delivery in any discipline.
  Papers focusing on APL, J, or other array programming languages are
  solicited.  Tracks with specific industry focus will provide to
  participants the opportunity to explore these tools in depth with
  colleagues sharing their interests.


  Please notify either program chairman via e-mail or Fax of your
  intention to submit a paper by providing an abstract by November 30,
  1995.  Prospective authors will be given complete formatting
  instructions for draft and final paper submission.    

  Draft papers (not longer than 5000 words) are due no later than
  January 31, 1996.  To avoid mailing delays, submission by e-mail or
  fax is encouraged.  Notification of the program committee decision
  will be sent to authors by March 8, 1996.

  Camera-ready copy of final papers must be in the hands of the
  proceedings editor no later than April 15, 1996.  Editor James Boyd
  will assist authors with preparation of final, camera-ready copy
  from electronic text.  Authors of papers included in the proceedings
  should plan to present them at the conference.

  The APL96 Software Exchange:

  SIGAPL invites you to send new and useful software to the APL96
  Software Exchange.  The Software Exchange is a good way to make
  your, or your firm's, skills and products more widely known. New GUI
  software is especially welcome.  Software from prior APL conferences
  is also welcome if it has been significantly improved or updated.

  Software received by April 30,1996 will be available to attendees at
  APL96. The conference package plus later submissions will be
  available by about October 1996 from SIGAPL, the BBS\APL, and via
  ftp at watserv1.uwaterloo.ca. Small files via UUENCODE, or further
  info, see addresses.  Software in APL, J, and related array
  languages is invited. English is preferred, and other languages are
  also welcome.  Include an ASCII read.me (lisez.moi, lis-mich.dok)
  file that briefly describes what the software does, and what
  software and hardware is needed to use it.  This year we want to try
  something new.  If possible, please also include an APLASCII (v1.4)
  version of any software that you submit (ftp APLASCII for your
  interpreter via watserve1.uwaterloo.ca).  You must include written
  permission to distribute any copyright software.  Without
  permission, we can't distribute copyright software.

(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 Manugistics APLW export to floppy:
     10 Manugistics APLW 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

January 22, 1996

re: APL companies/APL-skilled employment - Internet resources
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
announce a free joint venture employment information project 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. Now, with the implementation of its
Internet resources, the APL Skills Database is even better. One
Toronto-based software development company has already found a new
full-time employee for its APL division by using this service!

How does it work?

The APL Skills Database consists of an Internet Website and Email
facility, which allows both employers and employees to contribute and
browse employment information. Employers are encouraged to submit job
details to the database, which will be posted at our website, and will
also be broadcast by email to participating APL-skilled potential
employees and consultants. All incoming information and questions
about the project should be directed to our central email address, at:

The APL Skills Database website can be reached via the Toronto APL SIG
or the ACM SIGAPL sites at:


The Skills Database project is now also offering to post resume
information of APL-skilled consultants, contractors and employees who

and we'll post it on our website. Content of this information is up to
you, be as brief or as detailed as you wish, or if you already have
your own site on Internet, we'll point to it from our site. Please
submit resume information as ascii text or html format only.

How can I get involved?

The APL Skills Database is a free service offered by the Toronto APL
SIG and ACM SIGAPL. If you're an employer looking for APL skills, just
send us the details of the position being offered and we'll post them
on our website right away. APL-skilled persons who so wish will be
sent these incoming job notices via email as they arrive. Candidates
for employment requiring APL skills are encouraged to contact
employers and apply for the job if interested. Employers are also
encouraged to browse our resume database for APL-skilled
personnel. Please send all questions, job notices, or your desire to
participate in the project and subscribe to our email job posting

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 service.

yours sincerely,

Richard J. Procter
Information Coordinator - Toronto APL SIG
