SUBTTL	Revision history


COMMENT	\

1	Conception.
	17-Jun-86  GCO 10418  /DPM/JAD

2	Add revision history, zero relative file number when starting to
	process remote create, accept remote queue name from QUEUE when
	doing a remote queue list.
	18-Jun-86  GCO 10422  /JAD

3	Fix bug in NEBDCN which prevents us from releasing stale channels
	after we're done with them.
	27-Jun-86  GCO 10427  /JAD

4	Fix lower case conversion of /CHARACTERISTICS
	27-Jun-86  GCO 10428  /TL

5	Implement an output "fairness counter" which prevents a transfer
	request stream from running "forever" if it never gets blocked
	due to flow control, filling all available buffers, etc.
	30-Jun-86  GCO 10430  /JAD

6	Check ITN rather than object block on a QUASAR ABORT message.
	30-Jun-86  GCO 10431  /JAD

7	Handle remote DJM indigestion and either cancel or requeue the
	job depending on the error level.
	10-Jul-86  GCO 10436  /JAD

10	Move characteristics/forms handling routines into a module
	called "CHRFRM" so it can be loaded by QUASAR to check the
	arguments on a CREATE and clunk the user then.
	10-Jul-86  GCO 10438  /JAD

11	Add run log stuff.  Since DQS isn't smart enough to do pretty
	things with the "error text" blocks, make the run log look
	like just another file transfered.
	24-Jul-86  GCO 10452  /DPM

12	GETITM croaks when presented with a length of zero.  Handle
	zero "transparently" and return a zero to the caller.
	30-Nov-86  GCO 10472  /JAD

13	Fix error in LLST.7 which clobbers error text pointer.
	5-Jan-86  GCO 10483  /JAD

14	If QUASAR slips and sends a NEXTJOB msg and we have no free
	streams, send a REQUEUE msg instead of forgetting we saw
	the msg. Hopefully this may fix QUASAR RUJ crashes. Also
	change $STOPs to STOPCDs.
	1-Jul-87  GCO 10519  /LWS

15	Add SETU.1 + some, isolate stream number from AOBJN pointer
	before determining stream type.
	17-Jul-87  GCO 10535  /LWS

16	Teach NEBULA to return attributes in "response to setup"
	message. In NXTJOB, if call to SELDRV fails, send "response
	to setup" msg to QUASAR with %RSUNA (not available) code so
	QUASAR will "ignore" the stream for a while.
	26-Jul-87  GCO 10547  /LWS

17	Add rudimentary support for the DQS corporate standard.
	10-Aug-87  GCO 10552  /KDO

20	Add FTFBST and FTFTRL to control file burst pages and file 
	trailer pages (respectively).
	18-Aug-87  GCO 10555  /KDO

21	Make ABORT work.  Implement STOP/CONTINUE and REQUEUE.
	20-Jul-89  GCO 10673  /DPM

22	Do not default a characteristic if none specified by the user.
	This can cause problems when queueing to a remote queue which is
	a generic VMS queue.
	18-Apr-90  GCO 10687  /LWS
