BATCH AND PRINT ENHANCEMENTS OVERVIEW
-------------------------------------

New system service to communicate with job controller

JOBCTL, PRTSMB, INPSMB, QUEMAN, SUBMIT rewritten

Many new features

Many bug fixes

Cluster capabilities

MAJOR  CHANGES
--------------

$SNDJBC system service supersedes $SNDSMB and $SNDACC

    $SNDJBC[W] efn,func,,itmlst,iosb,astadr,astprm

    Old services continue to work at V3.0 level


Queue database

    A shared RMS file, not a mapped section

    Extends as necessary to indefinite size

UIC  BASED  QUEUE  PROTECTION
-----------------------------

Queues have protection specifying access
for system, owner, group, and world classes.


    R - allows user to see job attributes

    D - allows user to affect job

        (R/D access checked against owner UIC of job)


    W - allows user to submit job

    E - allows user to act as queue operator

        (W/E access check against owner UIC of queue)

FORMS  CAPABILITIES  EXPANDED
-----------------------------

DCL commands for form and characteristic definition

    DEFINE/FORM replaces FORMSTYPE.DAT

    DEFINE/CHAR replaces CHARTYPE.DAT


Forms definitions more versatile

    System-wide default form definition

    Form properties now include:

	form width and length
	margins
	wrap and truncate

Forms with same stock are automatically mounted

CLUSTER  FEATURES
-----------------

Queues are cluster-wide

Transparent cluster-wide job submission and queue management

Minimum and/or maximum printer block limit

Generic queues can have explicit target queues

New SET QUEUE command affects a running queue

SET QUEUE/ENTRY command can update any parameter

Improved handling of batch log creation failures

Restartable batch jobs

    SUBMIT /RESTART
    SET RESTART_VALUE=string
    DCL symbols $RESTART and BATCH$RESTART

Periodic $FLUSH of batch log files

    SET OUTPUT_RATE=time

Submit for another user

Submit with alternate CLI

Identify message contains job disposition

Notify message contains completion status

$SNDJBC can submit by file specification

$SNDJBC contains embedded logical name translation

SHOW  QUEUE
-----------

Interacts with job controller to obtain information


Displays all available information


Displays form and characteristic definitions


Allows general wildcarding in name


Assumes both if /BATCH and /DEVICE omitted


SHOW QUEUE/CHARACTERISTICS [wildcard-name]
SHOW QUEUE/FORMS[/FULL] [wildcard-name]
SHOW QUEUE[/ALL][/FULL][/BATCH][/DEVICE] [wildcard-name]

NEW  START/QUEUE  QUALIFIERS
----------------------------

        /ALIGN=(pages,MASK)
        /BACKWARD=pages
        /BASE_PRIORITY=n
        /BLOCK_LIMIT=([lower,]upper)
        /DEFAULT=(BURST,FLAG,TRAILER)
        /FORWARD=pages
        /GENERIC=(queue-name[,...])
        /LIBRARY=filename
