When you issue commands to an application using an MAI-OC session, it works in the same way as issuing commands using OCS. However, there are some special considerations for sessions with IMS applications.
MAI-OC lets you simulate a logical keyboard locked condition, as well as abbreviate commands, use function keys, and use NCL procedures to simplify control procedures for the application.
Any commands that can be issued from an OCS window can also be issued from an NCL procedure. Even NCL procedures operating in full-screen mode (for example, invoked through an FSPROC command) can make use of MAI-OC sessions.
