Online dump
The online dump feature allows you to generate a hard copy of the
command and data transmission taking place between the host
computer and the LPS.
Starting and ending dump sessions
The dump session is started with a START command when the LPS
is online and in the idle state. The online dump JDE/JDL used must
specify VOLUME HOST=OLDUMP and CODE=EBCDIC.
The dump session is terminated by either the operator ENDJOB
command or the offline operator command. Other online operator
commands during a dump session perform the standard functions.
Dump format
Each host command directs the printer to perform an operation, or it
provides control information used during printing of a report. The
operations performed are either print with carriage control, carriage
control only, or control, for example, load FCB. All print commands
and some control commands transmit data to or from the LPS. The
dump format is designed such that for each of these commands there
exists a HEADER and DATA segment.
The HEADER segment consists of six fields, shown in table 4-63.
The DATA segment consists of the input data in hexadecimal
transmitted to or from the host with EBCDIC translation based upon
the CODE command. Input data that cannot be translated is left as
blanks. Each line of data is preceded by a byte count in hexadecimal.
