abs(EXPR)
. If the value of
EXPR
is
integer or floating_ point, then
the value of the function is the standard absolute value.
ord (EXPR)
.
The inverse of char.
EXPR
must be a string of length 1.
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.
