Library objects

A library is a collection of objects that extend the calculator’s

fimctionality. You can execute objects in a library, but you can neither

view, nor edit them. You can obtain libraries from various web sites.

Installing and attaching a library

To install a libraiy, perfomr the following:

1. Copy the library to your HOME directory.

- from a PC, use the Coimectivity Kit.

- From another calculator, use the calculator-to-calculator

connection cable.

2. Install the library in a port.

To install the libraiy in a port, use the following commands. In the

conmiands, n is tlie number of the port in which you want to store your

libraiy, and Library_variable is Üre name of the variable that

contains the library. This is the variable that you created when you

copied the libraiy to HOME.

- In RPN mode, with Library__variable on stack level 1:

port_number STO

- In algebraic mode:

STO(Library_variable, port_number)

3. Attach the library. A library generally contains a special routine to

attach it. Tliis routine nms when the calculator re-boots. To reboot,

press simultaneously (OÑj and (£3), then release them.

You can use the ATTACH command to attach a library without re

booting. See Command Reference Part B for details on the ATTACH

command.

Some libraries need to be stored in port 0. Check tire dociunentation for a

library for more information.

A library has a libraiy number. The calculator uses this number to refer to

the libraiy. In File Manager, the library’s number appears as “Ijxxxx",

where xxxx is the library number.
