Name The filename may be up to 17 characters in IBM labels, and ANSI labels before standard
level 3. On ANSI level 3 and after, the HDR4 record provides overflow storage for up to
63 more characters of filename.
Set Name On multi-reel tape sets, a name identifying the set as a whole. Normally, this is just the
volume name of the first reel in the set.
Generation Like a major release number. The version field is a version within a generation. On
VAX/VMS systems, these two fields are mathematically related to the (single) version
number of disk files.
Created The date the file was created. This is a six character field, where the first character is
always a space. The next two are the year. The final 3 are the day within the year,
counting January 1st as day 1.
Blocks The number of blocks in the file. In HDR1 records, this is always zero. The correspond-
ing EOF1 or EOV1 contains the number of tape blocks written in the file on the current
reel.
