Some of these articles contain small fragments of C-like source code, but I suggest that doesn't make them either topical or interesting to most participants in the C and C++ newsgroups. I humbly suggest, yet again, that these discussions be restricted to comp.theory, and that users try to edit the "Newsgroups:" header even when replying to a cross-posted article. -- Keith Thompson (The_Other_Keith) Keith.S.Thompson+u@gmail.com void Void(void) { Void(); } /* The recursive call of the void */
