- Bywater BASIC Interpreter/Shell, version 1.11
- ---------------------------------------------
-
- Copyright (c) 1992, Ted A. Campbell
- for bwBASIC version 1.11, 8 November 1992
-
-
-
- DESCRIPTION:
-
- The Bywater BASIC Interpreter (bwBASIC) implements a large
- superset of the ANSI Standard for Minimal BASIC (X3.60-1978)
- implemented in ANSI C, and offers a simple interactive environ-
- ment including some shell program facilities as an extension of
- BASIC. The interpreter has been compiled successfully on a range
- of ANSI C compilers on varying platforms with no alterations
- to source code necessary.
-
-
- OBTAINING THE SOURCE CODE:
-
- The source code for bwBASIC 1.10 will be posted to network news
- groups and is available immediately by anonymous ftp. To obtain
- the source code, ftp to site duke.cs.duke.edu, cd to /pub/bywater
- and get the appropriate files. These are as follows:
-
- bwb110.zip Source code in ZIP compressed format, with text lines
- concluded with CR-LF. This is the appropriate version
- for DOS-based computers.
-
- bwb110.tar.Z Tar'd and compressed source code with text lines con-
- cluded with LF only. This is the appropriate version
- for Unix-based computers.
