SUBTTL Revision history
COMMENT \
***** Release 6.0 -- begin development edits *****
1 6.1094 20-Nov-87
Add OPRNEB as the ORION module that processes messages that
are processed on a remote node in the cluster and that have come from
a remote node in the cluster.
2 6.1098 22-Nov-87
Add an entry for the OPR MOUNT STRUCTURE command to tables
NBTOQR and QRTONB.
3 6.1136 9-Dec-87
Make routine N$FBLK global. Also, correct the way N$SQSR,
N$SMDA and N$SNEB pick up the system PID index for QUASAR, MOUNTR
and NEBULA.
4 6.1138 13-Dec-87
Fix bugs found as a result of debugging NEBULA. Add routine N$TEXT
to process TEXT messages that originated from a remote ORION.
5 6.1142 17-Dec-87
Add support for the SHOW STATUS TAPE/CLUSTER-NODE: and SHOW STATUS
DISK/CLUSTER-NODE: commands.
6 6.1146 17-Dec-87
Add support for the SHOW STATUS STRUCTURE/CLUSTER-NODE: command.
7 6.1157 4-Jan-88
If an illegal NEBULA message type is detected or if the sender of
the NEBULA message is not privileged, then set flag word G$NERR so the remote
operator will be informed.
10 6.1158 5-Jan-88
Change N$RDSM to send a FROM NEBULA DISMOUNT ACK (.NFDAK) instead of
a TO NEBULA DISMOUNT ACK (.NTDAK) to MOUNTR if NEBULA is not running.
11 6.1159 5-Jan-88
Add entries for SHOW STATUS DISK, SHOW STATUS STRUCTURE and SHOW STATUS
TAPE to table NEBSTR.
12 6.1164 6-Jan-88
Shorten the display lines in table NEBSTR.
13 6.1187 17-Feb-88
If there are no messages for a node, change the error code from E$NNK
to E$NMN.
14 6.1197 27-Feb-88
Don't log a FROM NEBULA DISMOUNT ACK message since the WTO message
is logged.
15 6.1205 1-Mar-88
Change routines N$MACS and N$TEXT not to call routine SPGOUT so as to
prevent picking up a second IPCF page for the outgoing message.
16 6.1210 2-Mar-88
Change the TO NEBULA DISMOUNT ACK message log file entry to indicate
that the message came from NEBULA instead of MOUNTR.
17 6.1225 8-Mar-88
Update copyright notice.
20 6.1247 5-May-88
Add support for the SHOW STATUS NETWORK-NODE and SHOW PARAMETERS
NETWORK-NODE commands.
