G dump generation record

The key for the type G dump generation record is the volume serial number followed by the time of the day (hhmmssth) in packed decimal format. The time of day is followed by the year and day (0cyydddF) in packed decimal format, where:

C

The digit representing the century.

0=1900–1999

1=2000–2099

YY

The last two digits of the year.

DDD

The day of the year.

F

A four-bit character that allows the data to be unpacked and printed.

Because the time and date are in packed decimal format, you must specify the key in hexadecimal. An example of the key used for a dump generation record on volume DUMP01 created at 12:55 p.m. on day 135 of the year 1997 is:
