Identifiers

Identifiers are used to denote a device, constant, or variable. For example, T_PANEL could
represent an AMX Touch Panel, PLAY could represent the first channel, and CD_SELECT could
represent the current compact disc player. There are certain guidelines for identifiers:

Keywords

Keywords are certain words reserved for Axcess functions. These are integral to the system and
cannot be redefined or used as identifiers. For example, PUSH is a keyword, and cannot be used as
an identifier.

Mainline

An Axcess program typically consists of several definition sections, such as DEFINE_DEVICE,
DEFINE_VARIABLE, and DEFINE_PROGRAM. Each definition section has a different function.
Not all definition sections are required for a complete program. However, the
DEFINE_PROGRAM section is required because it contains the program code executed by the
Central Controller. This section of program code is also known as mainline. It is executed
continuously as long as the Central Controller has power.
1. When the Central Controller is powered up, it first executes the code in the DEFINE_START
section.
Axcess Programming Language
Identifiers must begin with a letter followed by any combination of letters, numbers, or
underscores. No spaces are allowed.
Valid identifiers: "CD3", "TOUCH_PANEL"
!
Invalid identifiers: "3VHS", "CD PLAYER", "*RGB4"
!
The identifier must have fewer than 26 characters.
Identifiers are not case-sensitive.
Each identifier must be unique. Once you define VHS3, do not choose the same name for
a different identifier.
