7. 7Xerox ANSI standard labeled
tapes and unlabeled tapes
This chapter describes Xerox ANSI standard labeled and unlabeled
tapes. It also includes carriage control conventions and a sample
JSL.
Xerox labeled tapes
The Xerox/OSS accepts any of the following Xerox 9-track tapes:
• ANSI labeled tapes created under the CP-V system
• Unlabeled tapes whose data files conform to record formats,
blocking factor, and carriage control requirements of this
printing system
• Tapes with other label conventions if the data files conform to
the record format, blocking factor, and carriage control
requirements when these nonstandard labels are bypassed by
operator procedures.
Control Program-Five (CP-V) and ANSI labeled tapes
ANSI labeled tapes created under CP-V conform to the requirements
of ANSI Standard X3.27–1969 (refer to the ANSI tape section at the
beginning of this manual). Labels processed by CP-V and the
optional user labels are described in table 7-1.
Unlabeled tapes
Unlabeled tapes whose data files conform to the requirements of this
printing system can be processed by Xerox/OSS. Unlabeled file
arrangements and formats are shown in figure 7-1.
