The current user’s operating system group ID.



Return Value

A character string, or $Null. Cannot be reset by an application program.


The current user’s operating system group ID (if the operating system supports group IDs); otherwise, $Null.

You can use the $UserID and $GroupID system variables to build levels of security into your applications.

During a Zim session, you also can LOGIN to the software under any defined UserName (in EntitySet Users). $ZUserID and $ZGroupID are then set to the UserID and GroupID associated with UserName; $UserID and $GroupID (containing values taken from the operating system) are still available for use.
