一个小巧的BASIC解释器的源代码

This README-file is part of the source-code-package of yabasic. This package contains all sources for yabasic, but no executable. Therefore it is of interest only for those, who want to modify the program. All files are subject to the GNU-copyleft, have a look at the file copying.txt. The package contains the following files: bison.c --- bison-generated routines, coding the grammar of yabasic bison.h --- header for bison.c flex.c --- flex-generated routines for tokenization of the input yabasic.c --- hand-coded file, implementing the rest of yabasic yabasic.h --- header file to yabasic.c yabasic.dsp --- project file for yabasic and MS VC++ 6.0 yabinst.c --- source for the installation program resource.h --- resource file for installation program yabasic.ico --- icon for setup program and yabasic yabinst.dsp --- project file for installation program and MS VC++ 6.0 yabbison.txt --- bison input file yabflex.txt --- flex input file copying.txt --- GNU-copyleft file for all sources Note for developers: Anyone who is interested in modify the grammar of yabasic should do this under Unix. Because the main tools used to code its grammar (bison and flex) are available only (?) under Unix.
