_ Programmer−defined symbols, also called identifiers, are used to name the variables, procedures, lists, and widgets

that you define in a UIL module. For the most part, you can choose any name that you like for these items, although

the UIL compiler imposes three rules:

A name must be unique within a module.•

A name must begin with one of the characters A−Z, a−z, $, or _ and may contain these characters as well as

the digits 0−9.

•

A name must be no longer than 32 characters.•

Based on these rules, you can see that Alpha, $money, _tab, and moon44 are legal identifiers, while the following

symbols are not: 1993, 3DogNight, next−char, and ask_the_user_to_save_her_work_callback.

The main body of a UIL module is divided into several sections that group the different types of definitions and

declarations. Each section begins with the section name and ends at the start of the next section. The list below gives a

brief overview of the five sections supported by UIL: object, value, identifier, procedure, and list.

An object section defines the widget hierarchy and widgets in a user interface. The widget definitions may

include initial resource and callback settings. The other four sections are used to define named items that you

use for these settings. The object section is covered in detail in Section #suilobject.

A value section contains definitions of variables used as resource ...
