Subject: Announcing SR Version 2
Version 2 of the SR programming language is now available from the University
of Arizona by anonymous FTP or by mail. New features include shared global
variables and operations, circular imports, real numbers and math functions,
formatted I/O, a more general syntax with fewer special cases, a more robust
system with better error checking, true multiprocessing when run on a Sequent
Symmetry, and many additional enhancements.
Version 2 is tested on Sun4, Sun3, DECstation, SGI Iris, HP RISC and 9000/300,
NeXT, and Sequent Symmetry platforms. Code is also included for the DG AViiON,
IBM RS/6000, DEC VAX, Encore Multimax, Apollo DN, and others.
This is a "preliminary" release of version 2 in that we have a few more things
to do before we will consider 2.0 complete. However, even in current form it is
much more robust and feature-rich than version 1.1. We anticipate the official
release of version 2.0 this summer, in conjunction with the publication by
Benjamin/Cummings of "The SR Programming Language: Concurrency in Practice",
by Gregory R. Andrews and Ronald A. Olsson
SR is available by anonymous FTP from cs.arizona.edu. There are two compressed
tar files; be sure to transfer them in binary (image) mode. The files are:
/sr/sr.tar.Z: The SR programming language, including source code,
documentation in PostScript and troff form, checkout programs, and
examples.
/sr/vs.tar.Z: The extended verification suite, needed only if you're
going to modify the system or port it to a new architecture.
Electronic mail interfaces to FTP are available at BITFTP@PUCC.BITNET (for
BITNET members) or ftpmail@decwrl.dec.com (for anyone). For details, send
either server a message with ``help'' in the body.
If you pick up SR by FTP, please send mail to sr-project@cs.arizona.edu to let
us know. We'll also put you on the INFO-SR mailing list (see below) if you so
request.
SR is also available by mail on tape, Sun cartridge, or two 1.44 MB diskettes.
For details and an order blank, contact the SR project at the email address
above, or call (602) 621-8448, or send a FAX to (602) 621-4246, or write to:
