============================================================== PRE-RELEASE -- PRE-RELEASE -- PRE-RELEASE -- PRE-RELEASE ============================================================== 11/23/96 - This pre-release contains the SNOBOL4.EXE file only. The documentation is being prepared, but is not available at this time. 09/12/97 - Version 2.23 corrected problem of '?' pattern match operator not being recognised with PLUSOPS enabled. 03/16/98 - Version 2.24 corrected a problem with the SORT function causng the system to hang. SNOBOL4+ -- README.TXT SNOBOL4+ provides the entire Bell Labs SNOBOL4 programming language, including real numbers, external functions, and many extensions. The total size of the object program and data cannot exceed 300K bytes in this version. SNOBOL4+ was a commercial product that we created in 1984. It was first sold by Prentice-Hall, and then substantially upgraded and sold by us. We are now making it freely available because all of our current work is with SPITBOL, a high-performance implementation of the SNOBOL4 language. We previously offerred a free version with greatly restricted capabilities called "Vanilla SNOBOL4." This release of SNOBOL4+ should be used instead of Vanilla SNOBOL4. ----------------------------------------------------------------------------- SNOBOL4.EXE The SNOBOL4+ compiler and interpreter version 2.23. Type SNOBOL4 /H or SNOBOL4 /A for help. SNOBOL4 CODE provides interactive statement execution. CODE.SNO Interactive statement execution and function loader SOFTWARE LICENSE ----------------------------------------------------------------------------- SNOBOL4+ and the accompanying manual and programs are copyrighted material. However SNOBOL4+ is completely free, and there are no restrictions on its use. You may incorporate all or parts of SNOBOL4+ in your programs and redistribute it by any means. You can use it for personal or commercial applications. This applies to SNOBOL4+ only -- Catspaw's commercial SPITBOL product and its printed manual may not be copied. While we believe it is bug free, SNOBOL4+ is provided AS IS without any support or warranty, express or implied, including but not limited to fitness for a particular purpose. Contributions are not required or solicited. SNOBOL4+ is free because we believe many people would enjoy programming in SNOBOL4, if there was a version of the language that was widely available. Contributions are NOT requested. Enjoy and share it! If you become a SNOBOL4 fan, you'll want SPITBOL, our professional version. SPITBOL is a high-performance 32-bit implementation with execution speeds 6 to 10 TIMES faster than SNOBOL4+. It uses all available extended memory on your 386/486/Pentium. Besides MS-DOS, versions are also available for OS/2 2.x, Apple Macintosh, Sun 4/SPARC, RS/6000, Silicon Graphics, and IBM 370-390 series mainframes. We also carry all SNOBOL4 books in print, from beginner to advanced. Enjoy this taste of SNOBOL4, the standard for text manipulation, pattern- matching, and fun programming. We hope you develop an appetite. CATSPAW, INC., P.O. BOX 1123, SALIDA, COLORADO 81201 USA Phone: 719/539-3884, FAX: 719/539-4830, e-mail: info@SNOBOL4.com More SNOBOL4 information?
