What is it they do? > Is very necessary install GRX library or not? Bison and flex are utilities to generate code (in C) for lexical and syntaxic analysers. There are usefull only if you want to implement a new language or a grammar (for interpreting mathematical expression for example). GRX library will be usefull if you want to use djgpp in graphics mode. With it you will have all the materials to draw lines, boxes, characters in any graphic mode (unless you don't have the good driver for your graphic card). Eric.
