Specifying input parameters
Using LCDS Print Description Language 2-3
Report separation The two logical processing commands that can control report
separation online are BANNER and RSTACK. The BANNER
command specifies the detection criteria for traditional spooler
banner pages and their associated report boundaries. The
RSTACK command is used to detect other types of report
boundary indicator records called RSTACK records.
NOTE: After reports are processed they are managed and
printed as jobs.
(See also “Using logical processing,” in which these commands
are described.)
Record length The default record length for online systems is 150 bytes.
However, you may choose larger record lengths with the
following restrictions:
•
If the data record transmitted from the host exceeds the value
that is specified in the RECORD LENGTH parameter of the
initial JDL, the record is truncated to the length that was
specified in the initial JDL, and no warning is provided. (This
action is consistent with IBM 3211 or 4245 printers.)
• The online dump JDL specifies a record length of 150 bytes.
If you use a longer record length, modify the JSL to dump the
data accurately.
To select a record length longer than 150 bytes, you must
specify the new value for the RECORD LENGTH command. You
must also modify the LINE DATA to print the extended character
or record length.
Using the
VOLUME HOST
command for
online printing
One PDL command that must be specified for normal online
processing is VOLUME HOST=IBMONL. The HOST parameter
of the VOLUME command performs two functions:
•
Allows the printer to accept data from the online host
• Allows PDL to use a different set of defaults for the RECORD
and LINE commands.
Refer to the “VOLUME HOST” parameter section later in this
chapter for additional information.
Online recovery After a system failure, data acquired from the host and stored on
system disk is imaged upon system restart. Only data that was
being received at the time of the power failure is lost and must be
retransmitted.
