* 1 You can combine the contents of multiple function memory (fn) locations or graph memory
( Y n, r n, X tn, Y tn, X n) locations into composite functions. Specifying fn1(fn2), for example,
results in the composite function fn1 ° fn2 (see page 5-14). A composite function can consist
of up to five functions.
* 2 Metric conversion commands are supported only when the Metric Conversion add-in application
is installed.
