The ??ODT (Return from Menu-Assisted Resource Control) command returns processing of input to the CONTROLLER and the system. This command does not work unless an ODT was previously transferred to the data comm environment by the ??MARC primitive command.
Syntax

Explanation
The ??ODT command forces an ODT to leave the control of COMS/ODT/DRIVER and return to the control of the CONTROLLER and the system. Commands that begin with two question marks (??) (primitive commands) are then recognized by the system, and nonprimitive inputs are handled directly by the CONTROLLER.
