(* The command string is sent to the Controller in the ’PAGE-(page name)’ or ’PPON/
PPOF-(page name)’ format. The string is captured in the buffer for one panel and sent to
the other panel. If panels are combined using the DEFINE_COMBINE statement, the rou-
tine needs to be written only once, and the command is sent back to the same panel. *)
