HOW TO HANDLE ERRORS
EXAMPLE
5-4
GC34-0070
If the utility encounters a recoverable error,
it
prints an error message and reissues the
prompt. Recoverable errors are:
• Invalid ccchss
• Wrong number of arguments
• Device at specified device address not a diskette device
• End of file address you specified not within the data extents
• Data file extents in conflict with each other
• Invalid data fIle name
• Invalid device address
• Extents not in basic exchange data area
If the utility encounters an umecoverable error, it abnormally terminates the CREATE
operation with an abnormal cycle end message. The utility then recycles to the prompt
for the device address. The unrecoverable errors are:
• Data file overlaps an existing data file
• No available HDRls
• Extent arrangement indicator incompatible with the data file extents requested
• Name you entered duplicates one that already exists on the volume
• Unrecoverable I/O err_or
• VOLID is not compatible with the basic exchange data file
• Invalid HDRI on diskette
The following example shows a typical create HDRI session:
