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 X terminal connected to machine Y?
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?

        The APL95 Software Exchange: SIGAPL invites you to send new
        and useful software to the APL95 Software Exchange.  New GUI
        software is especially welcome.  Software from prior APL
        conferences is also welcome if it has been significantly
        improved or updated.  APL95 Conference Software will be
        available in three ways:

        - The Conference Package: software received by April 5, 1995
          will be available for purchase at APL95 in San Antonio.
        - The APL95 Supplement: software received between April 5 1995
          and June 8 1995 will be mailed at no charge to all who
          purchase the Conference Package at APL95.
        - The Conference Package, plus the APL95 Supplement, will be
          available by about October 1995 from SIGAPL, the BBS\APL,
          and the Waterloo archive.

        Send software for the APL95 Software Exchange on a 3.5" disk
        to:{*filter*} Holt, 3802 N. Richmond St. Arlington VA 22207 USA

        Software in APL, J, and any related language is invited.
        English is preferred, and other languages are also welcome.
        Please include an ASCII file that briefly describes what the
        software does, and what other software/hardware is needed to
        use it. Please include permission to distribute any copyright

        APL95, "APL Does It Today"
        SIGAPL's annual international conference for 1995 will take
        place between June 4 and June 8 in San Antonio, Texas.  The

        practical use of APL.  
        CONTACT INFORMATION: Two Internet distribution lists have been

        broadcasting information to the subscribers.  To subscribe,

        single line should read "subscribe APL95_info

        to be used for initiating conversations with APL95 Committee
        members. Someone will reply to your message as soon as

(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

*free usually means you can get it for free from the net, or pay small
media/documentation charges to get it from the vendor.
