between quotes that contain that local variable, and show the evaluated expression.

To activate the function in ALG mode, type the name of the function followed

by the argument between parentheses, e.g.,	. Some
examples are shown below:

Reference 2`1.2`@@@H@@@ @@@H@@@2/3`@@@H@@@„Ü2`@@@H@@@@@@H@@@

In the RPN mode, to activate the function enter the argument first, then press

the soft menu key corresponding to the variable name		. For example,
you could try:	. The other examples shown above can be
entered by using:	,	.
