The name of these variables is reserved and cannot be used for user-defined variables. The built-in variables describe the graphical element, the design file, system information or database information.

Some of these variables are read-only. If the variable is read-only, it will be indicated by READ-ONLY in the description below. When changing the value of a variable describing the properties of a graphical element (level, color, text font, text size, etc.), the element will be updated according to the new settings when the script exits.

INIT refers to variables that are automatically initialized before the script starts. Variables describing the attributes of a graphical element are automatically set to the proper value corresponding to the graphical element.
