Changing case in strings

How would one go about changing the case of letters in a string? Say you have a string "this.letters" being set letter by letter... and you want certain letters to be capitalized. Script example:

if (playerchats){
for (this.i=0;this.i<strlen(#c);this.i++){
if (!strequals(#e(this.i+3,1,#c),h)){
setstring letters,#s(letters) #e(this.i+3,1,#c);
} else {
setstring letters,#s(letters) capitlization thing here;
}
}

Now, lets say I wanted all the H's to be capitalized. How would I go about doing that where the blue text is? My idea was to use the new ascii command, and add/subtract the correct value from lowercase to uppercase, but then I'd need to know how to check the ascii of that particular letter...

Hopefully you people can understand that :o
