Dynamic UCBs
This application handles device addresses that have been dynamically configured into the system.
This application also recognizes when a dynamic I/O configuration change has taken place and displays the new configuration the next time you press Enter or the PF7/8 keys.
To reduce the overhead, the TAPE STATUS/Control application does not PIN the UCBs it displays. Therefore, if you use this application during dynamic reconfiguration processing, you might receive an 0C4 abend. This abend is a very rare occurrence and does not merit using the overhead that is required to circumvent the situation.
