Description
Important:
This parameter has been retained for compatibility, but should not be used when building new applications.
The parameter Undefined specifies the behavior when ObjectScript attempts to fetch the value of a variable that has not been defined. The value of Undefined may be 0, 1, or 2:
-
0 - Always throw an <UNDEFINED> error. (default)
-
1 - If the undefined variable has subscripts, return a null string, but if the undefined variable is single-valued, throw an <UNDEFINED> error.
-
2 - Always return a null string.

Instead of using the Management Portal, you can change Undefined in the Config.MiscellanousOpens in a new tab class (as described in the class reference) or by editing the CPF with a text editor
