SUBTTL	Revision history

COMMENT \

*****  Release 4.2 -- begin maintenance edits  *****

0			7-Jan-83
	Currently no edits

2	4.2.1582	20-Jul-84
	Check if the priority of a request has been changed and if so,
turn on EQ.CHP in word .EQSEQ in the EQ of the request.

3	4.2.1610	28-Feb-85
	In S$AFTR, for notification requests, set G$NTFY to -1. This will
insure that the notification request is sent to ORION.

4	4.2.1613	17-Apr-85
	Before an IBM node is shut down, ensure that both the reader and
printer are idle.

*****  Release 5.0 -- begin development edits  *****

10	5.1003		7-Jan-83
	Move to new development area.  Add version vector.  Clean up
edit organization.  Update TOC.

11	5.1162		21-Sep-84
	Add code to build SETUP message for starting SNA Workstation. Do
not allow requests to be scheduled for SNA Workstation printers and punches.

*****  Release 5 -- begin maintenance edits  *****
20	Increment maintenance edit level for GALAXY 5.

*****  Release 6.0 -- begin development edits  *****

25	6.1023		Oct-19-87
	Modify routine S$SHUT to process the shutting down of a remote LPT.

26	6.1042		Oct-29-87
	Add support for the handling of remote LPT objects and for the
scheduling of remote print requests

27	6.1045		Oct-30-87
	Correct errors in the SETUP routine introduced by remote LPT
setups that caused incorrectly formatted SETUP messages to be sent to
non-LPT processes.

30	6.1059		Nov-6-87
	Change routine CHKOBJ to not shut down remote LPT objects if they
have no pending job requests.

31	6.1067		Nov-9-87
	Add support to process NEXTJOB messages that come from LISSPL

32	6.1072		Nov-16-87
	Include the terminal characteristic name with the SETUP message.
Store the terminal characteristic in OBJTCR upon receiving the RESPONSE-TO
SETUP message, because it might have changed.

33	6.1083		Nov-17-87
	Include the length of the name block when adding a time event
queue entry at SETI.1.

34	6.1093		Nov-20-87
	Change routine IGNORE to pass the correct name block address to
routine A$FOBJ.

35	6.1097		Nov-22-87
	Use the $QACK and $QWTO macros instead of the $ACK and $WTO macros
when sending .OMACK and .OMWTO messages.

36	6.1123		Dec-6-87
	Indicate to routine N$CSTN by word G$DEFL whether or not the CREATE
request corresponding to the QE included a node name.

37	6.1124		Dec-6-87
	Have NEXTJB use only the attributes, rather than both the attributes
and unit number, from the QE when building a NEXTJOB message that is to be
sent to a cluster LPTSPL.

40	6.1173		Jan-27-88
	Check forms type when scheduling a LAT printer.

41	6.1223		7-Mar-88
	In routine SCHD.2: check for whether there is an outstanding forms
change message before finding a job for the object.

42	6.1225		8-Mar-88
	Update copyright notice.

43	6.1242		28-Apr-88
	Check the object block, rather than the QE, when determing if the
request involves a cluster or DQS printer.

44	6.1269		18-Oct-88
	In routine SHUT.4: include the message code in the SHUTDOWN message.

;CALL IS:	S1/ Pointer to the .QE

;
;NEXTJB performs the following operations:

;	2)  Move the queue entry from the processing queue to the USE queue
;	3)  Validate the account string
;	4)  Copy changable data from the .QE to the .EQ
;	5)  Send the request to the known component

;	routine gets called and all the data-structure associated with
