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
“I
jxxxx
",
where xxxx is the library number.
