Syntax:  UPPERCASE

  Changes the current word or the selected range to uppercase.

  If the word contains both uppercase and lowercase characters, LSE
  changes all letters to uppercase.  If the cursor is between words,
  LSE changes the following word to uppercase.  If a selected range is
  active, all the characters within that range are changed to
  uppercase.  The cursor then moves to the start of the next word.
