Syntax

$userid

Return Value

A number, or $Null. Can be reset by an application program.

Description

The current user’s operating system user ID; otherwise, $Null.

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

During any Zim session, you can LOGIN 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.
