Specifying input parameters

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:

Using the

VOLUME HOST command for online printing

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.

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.
