HOW TO HANDLE ERRORS
EXAMPLE
6-10
GC34-0070
If the utility encounters a recoverable error, it prints an error message and reissues the
prompt. Recoverable errors are:
• Response to the prompt does not have three parameters
• Invalid device address
• Device at specified device address not disk device
• Invalid sector address
• Starting sector address greater than ending sector address
If the utility encounters an unrecoverable disk I/O error, it abnormally terminates and
reissues the DISK AREA= prompt. If the utility encounters an unrecoverable operation
station or printer I/O error, it terminates.
The following is an example of a dump from the disk on the printer. The disk device
address is 003, with a starting sector address of 200130 and an ending sector address of
20013l.
