Bruce, You need to account for the whitespace in your string. Try this X = "abba butter bbb a"; StringReplace[X, StartOfString | (WordBoundary ~~ Whitespace) ~~ y_ -> ToUpperCase[y]] AbbaButterBbbA Cheers, Brian Bruce Colletti wrote: > Re v5.2.0.0. > > This code capitalizes each word's first letter: > > X="abba butter bbb a"; > StringReplace[X,WordBoundary~~y_->ToUpperCase@y] > > "Abba Butter Bbb A" > > However, I mistakenly thought StringReplace would substitute the full "WordBoundary~~y_" pattern by a capital letter to give "AbbaButterBbbA".

Is it this focus upon the substring that explains why the above code leaves WordBoundary untouched? Or is the "real" reason something else? > > Thanks. > > Bruce
