Because the calling frame remains open when a called frame is executed by an openframe statement, it is important that the calling frame be able to communicate with the child frame. Consequently, the openframe statement returns a reference variable of type FrameExec to the calling frame. For the calling frame to use this value, you must capture the FrameExec object of the child frame in a variable. The syntax is:

The calling frame can also use the returned FrameExec object with the SendUserEvent method to communicate with the child frame. For more information, see Inter-Frame Communication Techniques (see Inter-Frame Communication Techniques).
