o 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
Dickey at the University of Waterloo, this software is now

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 Dickey, Mathematics Department
University of Waterloo
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 available
on demand. Write to Lee Dickey at email@example.com
SIGAPL's updated Software Library guidelines are:
o 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
o 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.
o Put all of your material in one single .ZIP file for easy
o Include any needed copyright permissions. Copyrighted
software can't be distributed without permission.
o 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
o Check your software for viruses. Archive.waterloo.ca will
also check your software for viruses.
o Authors should pay special attention to the quality, usefulness,
and documentation of their work, and should include their name
and address (including email).
o Significant improvements and major updates of prior SL
software are welcome.

(12) Q: How do I pass APL functions from one APL to another?
A: 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 some options -
o 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.
o 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".
o Macintosh APL68000 export to floppy:
MOUNT'Untitled' <> )OUT 0 TRANSWS
In finder, change file name to "TRANSWS.ATF"
o Macintosh APL68000 import from floppy:
In finder, change file name to "TRANSWS" (without ".ATF"
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).
o Atari APL68000 export to floppy:
MOUNT 'A:' <> )OUT 0 TRANSWS
o Atari APL68000 import from floppy
MOUNT 'A:' <> )IN 0 TRANSWS
Problems: same as in point 2.
o IBM APL2/PC export to floppy:
)HOST A: <> )OUT TRANSWS
o IBM APL2/PC import from floppy:
)HOST A: <> )IN TRANSWS
Problems: none experienced upto now
o IBM mainframe export to floppy:
start APL with "APL2 CASE(2)" (necessary for underscored
)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
o IBM mainframe import from floppy
I have no experience with this, but I suppose:
Upload TRANSWS.ATF to file ...APLTF.TRANSWS
o APL2000 APL+DOS, APL+UNIX, APL+Win export to floppy:
o APL2000 APL+DOS, APL+UNIX, APL+Win import from floppy:
Problems: Different from IBM or APL68000 or "extended standard"
"A B C" is B, partioned enclose, squeezed quad,
monadic ",[1.5]", take with axis and scalar functions with axis.
o Dyalog APL:
Dyalog includes User Commands for workspace transfer; these are
documented in the Workspace Transfer Guide, supplied with Dyalog APL.
o APLX reportedly provides )IN and )OUT commands compatible with
APL2/PC and APL2/370.
o NARS2000 also supports migration through .atf files
written out by )OUT and read in by )IN.
o 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.
o VisualAPL from APL2000 provides two simple options for importing
APL code from legacy APL's:
o Select the APL code in the source APL's session and
Paste Special it into VisualAPL in Microsoft Visual Studio
o An ActiveX component is provided with VisualAPL to en
masse convert the legacy APL code to Unicode and store it in
a text file which can be used by VisualAPL.
VisualAPL does not use a proprietary workspace format for storing
APL code, instead it stores APL code in Unicode text files which
can be run as interpreted APL scripts or as compiled APL .Net
classes using Microsoft Visual Studio 2005/2008. VisualAPL Unicode
text files can also be directly compiled without Visual Studio
using the command line compiler provided with the Microsoft .Net
VisualAPL does not use a proprietary APL 'session', but instead
uses the mainstream Microsoft Visual Studio 2005/2008 IDE
[Interactive Development Environment].
All schemes suffer from the basic incompatibility between APL
vendors. This comes from extensions to standard ISO APL in several
o Different built in functions - the quad functions. This includes
file IO, graphics etc. Also the (mostly obsolete) ibeam
o Generalized arrays - boxes versus nests. A major fight in the
community for at least the last 10 years. Unresolved.
o User defined operators - not all implementations allow this.
o 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
Q:How do I write APL using only ASCII?
A: Writing APL in ASCII
Almost all vendors have provided ways to enter APL from non-APL
terminals. They took forms such as @BOX for example. For some reason
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.
