This message announces the availability of Scheme release scm4a10.

Dynamically added types now can specify an EQUAL? procedure.

I have added a new type called uniform vectors which uses less storage
than regular vectors.  Uniform vectors encompass bit-vectors, strings,
vectors, integer-vectors, float-vectors, double-vectors, and
complex-vectors.

Code has been reorganized and procedure newsmob() added.  New types
can now be added without modifying any of the distribution C files.

#! at the beginning of a file causes the first line to be ignored.
This allows scheme programs to be invoked as shell scripts on Unix
systems.

Scm conforms to Revised^4 Report on the Algorithmic Language Scheme
and the IEEE P1178 specification.  Scm is written in C and runs under
Amiga, Atari-ST, MacOS, MS-DOS, NOS/VE, VMS, Unix and similar systems.
ASCII and EBCDIC are supported.

Documentation is included explaining the many Scheme Language
extensions in scm, the internal representation and how to extend or
include scm in other programs.

SCM can be obtained via FTP (detailed instructions follow) from:
