In this version of OpenROAD, you can now perform a CALLFRAME as the result of a portlet interaction (where the CALLFRAME is issued from a guest frame) and optionally receive the same runtime and visual behavior as if the CALLFRAME was the result of a non-portlet field interaction—the simple case where portlets are not used. The called frame (through the CALLFRAME 4GL statement) will block the guest frame and optionally the portlet’s host frame.
