relatively simple and consists of two parts, contained between the program containers

• Input: x x

• Process: ‘LN(x+1) + EXP(x) ‘

This is to be interpreted as saying: enter a value that is temporarily assigned to the name x (referred to as a local variable), evaluate the expression 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., @@@H@@@

„Ü2`. Some examples are shown below:

In the RPN mode, to activate the function enter the argument first, then press the soft menu key corresponding to the variable name @@@H@@@ . For example, you could try: 2@@@H@@@ . The other examples shown above can be entered by using: 1.2@@@H@@@ , 2`3/@@@H@@@.
