 Description

     READUPDATED() is a Get system function intended primarily for creating
     new READ Layers.  It is identical in functionality to UPDATED() (see the
     UPDATED() entry in the Reference guide), except that it allows the
     UPDATED() flag to be set.

     READUPDATED() enables you to manipulate the UPDATED() flag from outside
     of the Get system source code.
