and get the result you want without having to type the expression in the right-

hand side for each separate value. In the following example, we assume you

have set your calculator to ALG mode. Enter the following sequence of

keystrokes:

„à³~h„Ü~„x™‚Å

‚¹~„x+1™+„¸~„x`

The screen will look like this:

Press the J key, and you will notice that there is a new variable in your soft

menu key (@@@H@@). To see the contents of this variable press ‚@@@H@@. The screen

will show now:

Thus, the variable H contains a program defined by:

<< Æ x ‘LN(x+1) + EXP(x)’ >>

This is a simple program in the default programming language of the HP 48

G series, and also incorporated in the HP 49 G series. This programming

language is called UserRPL (See Chapters 20 and 21 in the calculator’s user's

guide). The program shown above is relatively simple and consists of two

parts, contained between the program containers  :

• Input:

Æ 

• 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
