Returns boolean result indicating if the name passed as parameter corresponds to a routine or variable in the running script.

variable = object.IsDefined(name)

variable	Boolean	True if the name exist, False if not
object	ScriptManager2 or ScriptAggregate	Previously created ScriptManager2/ScriptAggregate object
name	String	The name to check

Remarks:

IsDefined method gives you a chance to see if a certain element is defined in the script. Therefore before using the host.script property to call a routine or acces a variable from the running script you can test if it exists and perform error handling or alternative action. 

Applies to:

ScriptManager2 and ScriptAggregate objects
