I'm running: XEmacs 21.4 (patch 14) "Reasonable Discussion" [Lucid] (i386-unknown-freebsd4.8, Mule) of Sun Sep 7 2003 on baloo.meduseld.net I've noticed that the interval quantifier (\{n,m\}) does not work when the preceding expression is an ordinary character, e.g. a So things like "a\\{4,4\\}" fail while "[a]\\{4,4\\}" do. So there is a work around. But to me this is very inconsistent, since the other operators like `*' and `+' (to which this construct is compared in the info doc) DO work with ordinary characters. If this is the intended behavior, then I think a doc update would save people time and effort (it took me a while to find this out.) Perhaps something like: N.B.: this operator only works with regexps using `special constructs' (q.v.). E.g. "[a]\\{4,4\\}" works and "a\\{4,4\\}" doesn't. -- / "I don't care who does the electing as long as I get to do the davep (|) nominating" / -- Boss Tweed $$$$
