We are happy to announce the first release of GW-Ada/Ed for the Apple
Macintosh family of computers. This software is now available by
anonymous ftp from wuarchive.wustl.edu, in the directory
languages/ada/compilers/adaed/gwu/mac.
This project was sponsored by The George Washington University, and in
part by the United States Advanced Research Projects Agency (ARPA) under
contract #FY3592-93-10234, administered by Phillips Laboratory, Kirtland
AFB, NM 87117-5776.

I. ABOUT THE GW-Ada/Ed-Mac DEVELOPMENT ENVIRONMENT
GW-Ada/Ed-Mac is a development environment built around the New York
University (NYU) AdaEd compiler/interpreter. It allows the editing,
compiling, binding and execution of Ada 83 programs. GW-Ada/Ed-Mac was
supervised by Prof. Michael B. Feldman. Manuel A. Perez, a GWU doctoral
student in Computer Science, is responsible for the Macintosh version,
including the editor and developer shell.
NYU's original README file is included in the distribution, for your
information. In summary, Ada/Ed was developed several years ago, and
validated under the Ada Compiler Validation Capability suite then in
effect. Ada/Ed is a full-scale compiler, which generates instructions for
a virtual machine. Execution is carried out by an interpreter for this
virtual machine.
Ada/Ed handles nearly all of Ada 83, including tasking and generics.
Not supported are a number of machine-dependent features, most of which
are not sensible to support in a virtual-machine environment.
The multi-window editor follows the usual Macintosh menu and command-key
conventions. Source files are limited to 32k characters, however.
Standard output is sent to a subset-VT100 console window, so that cursor
addressing and other ANSI escape sequences are supported. We think that
the system will be fun to use and as easy to work with as most Mac
programs are. Students who have tested the system comment that it, like
GW-Ada/Ed-DOS, is a great way to learn Ada.

II. ACQUIRING AND INSTALLING GW-Ada/Ed-Mac FROM AN FTP ARCHIVE
System requirements - a Mac with a 68030 or 68040 processor, System 7, and
at least 4mb of RAM. You should have around 10mb free space on your hard
disk, too. The program will not run under System 6; we have not tested with
or with a 68020 processor. You are welcome to try, but we make no promises.
You need to copy and download four files, in addition to the readme.

-rw-r--r-- 1 mfeldman users 155782 Jan 21 15:14 adaprogs.sea.hqx
-rwxr-xr-x 1 mfeldman users 1227749 Jan 21 14:42 gw-adaed.sea.hqx
-rw-r--r-- 1 mfeldman users 11907 Jan 21 16:05 userman.mac
The first file is the original NYU document for Ada/Ed; you don't need it
to run this system, but it contains useful background information. The
last file is a brief user manual for GW-Ada/Ed-Mac; you can open it with
any ASCII editor or Word Processor; we recommend that you open it with the
GW-Ada/Ed-Mac editor, once you've installed the system.
The files gw-adaed.sea.hqx and adaprogs.sea.hqx are BinHex-ed
self-extracting Stuffit archives. Once you've downloaded the files to your
Mac, you need to use the BinHex utility program to un-encode them. BinHex
is a free program that you can pick up from any Mac archive or user group.
The folder named "GWU AdaEd Folder" contains a file icon "GWU Ada"with a
version number. This is a double-clickable application. The other files
are not. Do NOT move or otherwise disturb these files! GW-Ada/Ed expects
to find those files, and behavior will be unpredictable if you mess with
them. The folders GWUDemos, NYUDemos, and Spider contain sets of
interesting programs to de,onstrate the capabilities of GW-Ada/Ed-Mac and
of Ada in general. GWUDemos was produced by GWU, NYUDemos by NYU, and
Spider by John Dalbey of California Polytechnic State University at San
Luis Obispo.
Once all four folders are available on your Mac, start reading the user
manual, which gives a brief tutorial on using the system.
We would like to have some idea who is using our software, and therefore
request that you make contact by e-mail to let us know how you like it.
