Declaring Global and Universal Variables
On this page:
Global Statement
Use a global statement to declare global variables, which can be accessed from any script within a document. Global variables must be declared within each handler where they are used. See Containers for more information on global and universal variables.
Syntax:
Syntax definitions for language elements follow these formatting guidelines:
- boldface: Indicates words and characters that must be typed exactly
- italic: Indicates expressions or other variable elements
- {} (curly braces): Indicate optional elements.
- [] (square brackets) separated by | (vertical pipes): Indicate alternative options where one or the other can be used, but not both.
Example syntax:
In this example, "open file" is required and must be typed exactly. "fileName" is a variable element; it is the path to and name of the file being opened. The following expression is optional and indicates why the file is being opened. If this expression is added, "for" is required and must be typed exactly. One of the following must be included, but only one, and they also must be typed exactly: "reading", "writing", "readwrite", "appending", or "updating".
To see simple examples of two different ways of using global variables, see Global Variables in the Examples section.
Universal Statement
Use a universal statement to declare universal variables, which can be accessed from any script during the current run of the host program. Universal variables must be declared within each handler where they are used. See Containers for more information on global and universal variables.
