From: Fraser Dickson on 5 Mar 2010 10:21 Hi I have a string with 3 words in it "BLUE RED GREEN" I want it all to be in lower case except the first letter of each word . i.e "Blue Red Green" I know how to convert it all to lower case but im unsure how to keep each of the first letters as capitals. Thanks

From: Fraser Dickson on 6 Mar 2010 06:00 Ah Thanks Us Its nearly exactly what i want but is there a way to also get it to work when a word only has one letter in it i.e s = " A GREEN CAT" your code will produce A green Cat whereas i would want A Green Cat Thanks for your help Fraser

Dear Fraser! > Hi I have a string with 3 words in it > "BLUE RED GREEN" > > I want it all to be in lower case except the first letter of each word . i.e > "Blue Red Green" > > I know how to convert it all to lower case but im unsure how to keep each of the first letters as capitals. So how is your problem defined algorithmically? All characters in lower case, but the characters following a space and the first character in upper case. S = "BLUE RED GREEN"; S = lower(S); ind = [1, findstr(S, ' ') + 1]; S(ind) = upper(S(ind)); This is more trivial then the nice REGEXP approach. It fails if the last character of S is a space.
