Record structure
A record is arbitrarily divided into two portions: operating system
and user.
• The operating system portion of the record contains
information that is supplied by the host operating or spooling
system.
• The user portion of the record contains information that is
provided by the application or the program that is running on
the host system.
The boundary between the two portions of the record is
traditionally between the record length and the printer carriage
control (PCC) fields. The PDL RECORD command defines the
components of a record.
Offline dump
The offline tape dump feature is a troubleshooting tool for tape
jobs. It allows you to generate a hardcopy printout of all the
characters, carriage control information, tape labels, and other
information in the data stream, while a job is being transmitted
and printed.
Offline dump
format
• When the system encounters a tape mark while formatting for
the dump, the tape mark is indicated following the block
number.
• The dump of each block, tape mark, end of volume, or end of
data is separated by at least one blank print line.
Dump content The tape data stream dump contains the following information for
each block that is dumped:
• Block number
•Blocklength
• The hex decimal number of the starting byte in each printed
line of data
• The data printed in hexadecimal
• The data printed using the translation code table that is
defined in the VOLUME CODE command.
