Overview

The Control-M/Tape interface for displaying messages on cartridge magnetic tape subsystems allows you to

• display the first seven characters of a pool name on the cartridge drive LCD display when a scratch tape is requested from a specific scratch pool
• stop automatic cartridge load when two consecutive tape mounts result in the rejection of the mounted tapes

  To enable this feature, the Cartridge Stack Loader (CSL) must be set to SYSTEM mode.

The IGXMSGEX Message Display Installation Exit enables you to customize messages to be displayed on an IBM 3490 tape drive. This exit is optional and is invoked only if it is link-edited with the Message Display Execution Module (IGX00030).
