SPOOLING
	--------

The DEC print spooler has been abandoned because it is unable
to alter its action once a file has been queued to it. It 
could also crash a system by depletion of pool space. It is
unlikely we shall return to a task by the name of PRT... to
enable DEC software to spool files since the default for most
DEC software is to spool listing and dump files for listing
and deletion.


All queue entries are now processed by the program "...QUE"
which accepts standard format commands. The switches are as
follows:

Function:
---------
	/IN	Insert an entry
	/RM	Remove an entry
	/LI	List all entries ( no other switches apply)
	/AB	Abort current entry ( HP and PL only)
Queue:
------
	/BA	Batch queue		! SUbmit file
	/HP	HP plotter queue	! HPplot file
	/LA	LA36 printer queue	! SPool  file
	/LP	ANELEX printer queue	! PRInt  file
	/PL	CIL plotter queue	! PLot   file
Control:
--------
	/CM	Compatible mode	(ineffective - HP only)
	/CO:nn	Copies	(not used by any despooler )
	/DE	Delete file after spooling (all spoolers)
	/NF	No form feeds on listing   (LP & LA)
	/SP:nn	Speed 1-36. for HP only.

On a queue insertion ( except batch ) the relevant spooler
is called to begin despooling. If a file was being de-
spooled and the system crashed or the spooler crashed this
file will be restarted.
 
 The queue system as setup requires a file [1,7]QUEUEMAN.SYS of
fixed record size 64 bytes. 


Despoolers
----------

BATCH		BA....		SUbmit filespec	 DE

The batch spooler accepts a file of commands in a fixed format
and inserts these over a virtual terminal. It records all use
of that terminal in a log file { filespec.LOG }. The batch
stream is started either by "RUN BA...." or by the rescheduled
starting of the queue at 6pm every day. ( RUN BA..../RSI=24H )

HP flatbed 	HP....		HPplot filespec	 DE SP:nn CM

This plots a file ( default name PLOTFILE.PLT ) on the flatbed
The plot may be aborted by "QUE /HP/AB". Entries should not be
made to the plotter queue when the plotter is switched off.
To set up the plotter for a plot: (a) switch on plotter,
(b) press CHART LOAD, position the paper, press CHART HOLD,
(c) type the command "HP plotfile", (d) when the plotter
completes its initialisation it will stop with ENTER lit, at
this point press LOWER LEFT and then ENTER, the plotter will
then complete initialisation and commence th plot. For further
plots you can give the terminal commands at any time, but each
time a plot is about to be output the plotter will stop with
the ENTER light lit awaiting confirmation that the paper is 
present for the next plot

CIL plotter	PL....		PLot filspec	 DE

This plots a file on the CIL plotter which may be aborted by
the command "QUE /PL/AB". The default name for a file to be
plotted is PLOTFILE.PLT. In this case also the plotter should
be switched on and the paper and pen checked before plotting.

LA36		LA....		SPool filespec	 DE NF

This spools a file to the upper and lower case printer. To
abort a  file being output type <^S> on the LA36 then position
to top of form. Then type <^O> <^Q>. The next file should then 
be started by the spooler.

ANELEX		LP....		PRInt filespec	 DE NF

This prints a file on the Anelex lineprinter. It may be aborted
by pressing OFFLINE then TOP OF FORM and then ONLINE. The 
spooler detects a break in the paper in the Anelex and the 
state where the Anelex is offline or claimed by another machine


QUEUE COMMANDS	- EXAMPLES
--------------------------

QUEUE myfile.lst/RM/LA		remove the entry for myfile.lst
				to be output on the LA36
QUEUE plotfile.plt/IN/PL	append plotfile.plt to the queue
				for the CIL plotter
QUEUE	/AB/PL			abort the file being output on
				the CIL plotter
QUEUE	/LI			List all the queue entries

CCL COMMANDS
