GNU Flex has a C++ mode, where the lexer it generates is a class rather than a set of global variables and functions. It also lets you provide your own yyinput function, where you fill Flex's buffer from whatever source you want, including a stream. (In C, you can also simply provide your own FILE* value, which is usually a file, but can also be any other C file handle.) > (2) Are there any other tools similar to lex/yacc, commercial or open > source that can generate Delphi code?

You might try asking on the comp.compilers newsgroup. -- Rob _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi
