Afaik the latter. You specify what is not allowed rather than which are allowed. But sourcecode edited on multiple platforms might be a problem, (e.g. ligatures, denormalization and other forms of slightly different characters), this could lead to making the comparison of identifiers expensive, which is what you don't want in a compiler. But I don't know how big that problem would be. Maybe it is negiable. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
