476 Libraries

If the folder has been inadvertently deleted, you must create it before attempting to

use libraries.

You can define library objects using either the Program Editor or the Calculator

application. Library objects must be defined with a Define command and must reside

in the first problem of a library document.

Note: If you use the Program Editor to define a library function or program, you must

store the object and also save the document. Saving the document does not

automatically store the object. For more information, see Programming.

Naming restrictions apply to library documents and library objects.

• A library document name must be a valid variable name between 1 and 16

characters long, and it must not contain a period or begin with an underscore.

• A library object name must be a valid variable name between 1 and 15 characters

long. It must not contain a period and must not begin with an underscore.

Private and Public Library Objects

When you define a library object, you designate it as private (LibPriv) or public (LibPub).

Define a=5

a is not a library object.

Define LibPriv b={1,2,3}

b is a private library object.

Define LibPub func1(x)=x^2 - 1

func1 is a public library object.

A Private library object does not appear in the Catalog, but you can access it by typing

its name. Private objects serve well as building blocks that perform basic, low-level

tasks. Typically, private library objects are called upon by the public functions and

programs.

A Public library object appears in the Catalog’s library tab after you refresh the

libraries. You can access a public library object through the Catalog or by typing its

name.

Mac® only: In version 1.4 of the software, a library document name cannot contain

extended characters, such as Ö, á, or ñ.

immediately following the Prgm or Func line is automatically displayed as help in the

Catalog. You could, for example, show a syntax reminder there.
