Application Launcher supports all valid Windows 98 and Windows 2000/XP environment variables. The value of the variable must not exceed the length of the Application object name; otherwise, the variable fails.
Here are a few examples:
NWLANGUAGE
TEMP
PATH
When using an environment variable, you must enclose it in % characters (%PATH%).
For information about using the macros in a valid Application object property, see Section 49.8, Application Object Properties Where Macros Can Be Used.
