Requirements and Restrictions

Format




cuu
is a 3-digit hexadecimal tape device address.

Additional Information

This command uses 10 times the normal number of retries while attempting to write a tapemark. Therefore, it sometimes succeeds even if the tape labeling routines (for example) failed to write trailer labels.

Examples

Tapemarks are written to the tape on the 482 tape device in the following example.
