This message announces the availablility of Scheme release scm2d. All bugs that were reported have been fixed. Scm now has an error, system, and read-string! functions, file positioning, and can open files for simultaneous reading and writing. Scm conforms to Revised^3.99 Report on the Algorithmic Language Scheme [Draft August 31, 1989] and the IEEE specification. Scm runs under Unix and similar systems, VMS, and MS-DOS. Scm is interpreted and has 30 bit immediate integers for numbers. 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 except on VAX and SUN-4. Stack (escape) call-with-current-continuations are supported on all machines. ASCII and EBCDIC are supported. Documentation is included on the internal representation and how to extend or include scm in other programs. ftp altdorf.ai.mit.edu [18.43.0.246] (anonymous) cd archive/scm This directory contains the distribution version 2d of scm. `scm2d.shar' is a shar file of the C code distribution. `scm2d.tar.Z' is a compressed tar file of the C code distribution. `test.scm' is Scheme code which tests conformity with the IEEE spec. It is included in the shar and tar files. I will include additions that are mailed to me. `utils.scm' contains Scheme code for tracing functions as well as provide and require. `public.lic is the GNU General Public License. Be sure to get and read the GNU General Public License (public.lic). It is included in the shar and tar files. To receive an IBM PC floppy disk with the source and executable files send $50 to Aubrey Jaffer, 84 Pleasant St. Wakefield MA 01880, USA. 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).
