NOTE: Variables can also be used to represent part of the name of an existing variable in an expression. When this method is used the name of the variable is resolved and then the contents of that variable are used for further resolution of the expression. (For more information, see the examples later in this chapter.)
A Notification message can include an Variable expression as part of its text; however, it cannot assign a value to a variable.
The following syntax rules apply to Variable expressions:
Only one expression can be placed on a line.
No spaces are allowed before the "=".
Spaces that immediately follow the "=" are ignored.
Variable names and values are case sensitive.
Strings of alphanumeric characters do not require quotation marks. If quotation marks are used, they are considered part of the string.
