User trailer label
The user optionally may specify up to eight user trailer labels, UTL1
through UTL8. If used, these labels follow the file trailer labels. The
contents of these labels are contained in table 6-8.
Tape configurations
The organization of standard labeled tapes varies from user to user.
For example, optional labels may or may not be included, and tape
files may occupy many volumes. The four basic configurations that
can be processed by the printing system are enumerated below. An
example of a standard label tape for each configuration is contained
in the figure referenced.
• Single file, single volume (figure 6-3)
• Single file, multi-volume (figure 6-4)
• Single file, multi-volume (figure 6-5)
