Creating a JDE or JDL

XEROX DOCUPRINT 180 LPS PDL REFERENCE
This section explains how to create a JDE or JDL, DJDE processing,
online optimization and copy-sensitive copy modification entries
(CME).
An online job descriptor library (JDL) and its job descriptor entries
(JDEs) are created by the user according to the same rules and
syntax as other entries. The 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 LPS to accept data from the online channel
•
Allows PDL to use a different set of defaults for the RECORD
and LINE commands.
The defaults which are automatically selected when VOLUME
HOST=IBMONL is specified are as follows:
RECORD LENGTH = 150
LINE PCCTYPE = IBM3211 or IBM4245
DATA = (0,150)
If ANSI carriage control commands are used in the host application
program, the host operating system converts each command to a
valid 3211 or 4245 command before sending it to the printer. Any
commands other than those listed are rejected by the LPS online
interface (and by the 3211/4245). Therefore, the only appropriate
PCCTYPEs for an online JSL file are IBM3211 or IBM4245. Figure
4-4 shows a sample online JDL file that includes the PCCTYPE
parameter.
Because the carriage control command is sent prior to—rather than
as part of —the data record, offset to fields (such as DJDE prefix and
font index) are typically one byte less for online than offline, where
the carriage control byte is part of the data record. For the same
reason, the online DATA parameter of the LINE command has a
default offset of zero rather than one.
