          /* Create a font of only capital letters */
          capitals = extract_font_range(myfont, 'A', 'Z');

          /* Now transpose the characters in the font so that they will be used */
          /*  for the lower case letters a-z */
          transpose_font(capitals, 'a'-'A');
          textout_ex(screen, capitals, "allcaps",
                     100, 100, makecol(255,255,255), 0);

RETURN VALUE
       Returns 0 on success, -1 on failure.
