SUBTTL Revision history
COMMENT \
***** Release 4.2 -- begin maintenance edits *****
0 7-Jan-83
Currently no edits
***** 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 5.1008 18-Jan-83
Fix the GET.NETWORK.TOPOLOGY routine to analyze the error from
the NODE JSYS and if it needs a larger argument block, get one and try
again.
12 5.1162 21-Sep-84
Add code to handle SNA Workstation going online/off and code to
delete NAB and NOB when SNA Node is purged.
13 5.1172 22-Oct-84
In routine N$SACT if an SNA node is redefined as a termination actual,
call N$NNET to purge and recreate the node database entry.
14 5.1183 30-Nov-84
Get rid of GET.NETWORK.TOPOLOGY. Also, only check IBM nodes for
online and offline.
***** Release 5 -- begin maintenance edits *****
20 Increment maintenance edit level for GALAXY 5.
***** Release 6.0 -- begin development edits *****
25 6.1026 19-Oct-87
Add support to the ROUTE command for remote printers.
26 6.1042 29-Oct-87
Add support for the management of remote LPT objects and the
scheduling of remote LPT objects.
27 6.1097 22-Nov-87
Use the $QACK and $QWTO macros instead of the $ACK and $WTO
macros for sending .OMACK and .OMWTO messages.
30 6.1126 7-Dec-87
Do not schedule a print request to a TTY: printer unless its
unit number has been specified in the print request.
31 6.1132 7-Dec-87
When matching a QE with the source object in the route table, if
the node and object types agree and if the request has a %GENRC attribute,
then allow for a match.
32 6.1168 20-Jan-88
Undo edit 30
33 6.1177 11-Feb-88
Add support for specifying that batch log files and spooled files
be scheduled on specified local printers.
34 6.1225 8-Mar-88
Update copyright notice.
35 6.1233 5-Apr-88
For generic print requests in which the QE matches the source object
in the route table, but the target object in the route table does not match
the current object being matched in the object queue, then do not assume that
the current object is in the route table; rather, search all the remaining
source objects in the route table that match with the QE before comparing the
QE with the current object.
36 6.1253 10-May-88
Upon a match of a QE with a source object route table entry, first
check if the target object is .INFIN, if it is, then consider a match to
have occurred.

SUBTTL PURGE.DUP.OBJS - ROUTINE TO PURGE DUPLICATE OBJECTS
;This routine is called because it is possible to start the same
;device at the same node using both the node name and node number.
;This works only if the node is offline, since QUASAR cannot
;validate the Node. For example, if an operator said:
;Start Pr 0/Node:MUMBLE and Start Pr 0/Node:10 and node MUMBLE
;and node 10 are the same node, then you have a problem when
;the node comes online. This routine is called when a node comes
;online and it schedules a shutdown for the duplicate node.
;CALL: AP/ Node DB Address of Node which came online
