I don't think there's any sane way to do this with a single POSIX regexp (I think I could do it in one with a Perl RE, but it would be ugly); I'd love to be proved wrong though. . bar=rereplace(foo, "([^0-9])\.([^0-9])", "\1 \2", "ALL") would be safe, but would miss (say) "a.5"; you don't say what you want to do with multiple periods either... My inclination would be to do it in three bites: replace the periods you *want* to keep with a character guaranteed not to be in your string, say SOH, (you can always do a zero'th pass to strip such out), replace all remaining periods with spaces and finally restore the periods you want: temp=rereplace(foo, "([0-9])\.([0-9])", "\1#chr(1)#\2", "ALL"); temp=replace(temp, ".", " ", "ALL"); bar=replace(temp, chr(1), ".", "ALL"); It's not what you asked for, but it *is* only one regexp :) -- Pete Jordan ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Logware (www.logware.us): a new and convenient web-based time tracking application.
