In fact, most preprocessors allow you to do the following cute trick: #define wombat(x) wombats/**/x so that wombat(fred) expands to wombatsfred. No; the objections are that "//" is not an identifier, and only identifiers may be #define'd; and that it doesn't work (as has been pointed out) to give a line commenting feature. -- Tim Maroney, Carnegie-Mellon University Computation Center ARPA: Tim.Maroney@CMU-CS-K uucp: seismo!cmu-cs-k!tim (supposedly) "Remember all ye that existence is pure joy; that all the sorrows are but as shadows; they pass & are done; but there is that which remains."
