This message announces the availablility of Scheme release scm3a.  All
bugs that were reported have been fixed.  Real and complex numbers are
now supported.  Full continuations under VMS are now supported.
Initialization files are now supported.  Functions program-arguments,
getenv, tmpnam, software-type, get-internal-run-time,
get-internal-real-time, substring-move-left!, substring-move-right!,
and try-load have been added.  Variables *features* and
*load-pathname* have been added.  Constants char-code-limit,
most-positive-fixnum, most-negative-fixnum, and
internal-time-units-per-second have been added.

This is an alpha release; please do NOT post to comp.archives.

Scm conforms to Revised^3.99 Report on the Algorithmic Language Scheme
[Draft August 31, 1989] and the IEEE specification.  Scm runs under
VMS, MS-DOS, Unix and similar systems.

Scm is interpreted and tail recursion is implemented for interpreted
code.  Scm uses and garbage collects off the C-stack.  This allows
routines to be written in C without regard to GC visibility.  Full
call-with-current-continuations are supported.  ASCII and EBCDIC are
supported.

Documentation is included explaining the internal representation and
how to extend or include scm in other programs.

If you like scm you can support the developement and maintainence of
it by buying a disk from me or by sending money to the above address.
Money received will also help speed the release of a free symbolic
mathematics system (written in scheme).

P.S.  I have been having trouble with e-mail.  If you have sent me a
message and received no reply from me, cranky mailers is the reason.
