NAMEusetat - Replaces a character in a string. Allegro game programming library.
DESCRIPTIONReplaces the character at the specified index in the string with value `c', handling any adjustments for variable width data (ie. if `c' encodes to a different width than the previous value at that location). If `index' is negative, it counts backward from the end of the string. Example:
usetat(text_string, 2, letter_a);
