Miscellaneous.

1. abs(EXPR)
   . If the value of
   EXPR
   is integer or floating_ point, then the value of the function is the standard absolute value.

2. ord (EXPR)
   . The inverse of char.
   EXPR
   must be a string of length 1.

3. font(EXPR, EXPR)
   . Macintosh version only. Both arguments should be integer. The first controls the font, the second the point size. The relation between numbers and fonts is dependent on the fonts loaded, so you need to experiment. If an argument is not an integer, that parameter is unchanged. The result is a pair, where the first element is the old font and the second element is the old size.
