Once a session has been established through the Virtual 3270 Interface and has made an initial menu selection that passes control to an NCL procedure, the procedure begins the conversation by issuing an &PANEL statement. This results in a 3270 data stream being sent to the interface.
The interface user must issue a Receive call at which time the virtual panel image and Field Descriptor List are built and returned to the caller.
By requesting a Send (or a Send then Receive) function, any input is returned with the appropriate attention key set. This satisfies the &PANEL statement at which time the procedure can examine the input fields through their token names, and the key through the &INKEY system variable in the usual manner.
