 In the event of a crash a crash message will appear on TT0: requesting
 that a scratch tape be mounted for taking a CRASH DUMP of the 
 system.  After it is mounted the CONTINUE switch is pressed and the
 system dumped to tape.  The Utility CDA may then be used after rebooting
 the system, to analyze the cause of the system crash.  For further
 HELP with CDA type  HELP CDA keyword    where keyword is one of
 the following.
 
	COMMANDLINE		The CDA commandline and its use.
	SWITCHES REPORT		CDA report selection switches.
	SWITCHES FUNCTION	CDA function control switches
 
2	COMMANDLINE
 Since we only dump to magtape, the command line is
 
	[listfile/sw],[binary file/sw]=symbol file/STB,crash-input[/sw]
 
	listfile	A readable crash report sent either to TI: or
			a disk file.
	binaryfile	An optional binary file.  A magtape dump
			can be transfered to disk for faster access.
 
	symbolfile	DK0:[1,54]RSX11M.STB
 
	crash input	Either MM0:, or a disk file specifier.
2	SWITCHES
 CDA supports two groups of switches, report selection switches and
 function control switches.
	type HELP CDA SWITCHES REPORT
	 or  HELP CDA SWITCHES FUNCTION
3	REPORT
 The CDA report control switches should be placed on the crash-input specifier.
	/ACT		List Task Control Blocks for each active task
	/ALL		List output of all analysis routines.
	/CLQ		List the contents of the clock queue.
	/DEV		Lists information on all devices in the system.
	/DUMP:a:b	Dumps memory contents between addresses  a  and  b.
	/HDR		Lists the contents of the task headers for each
			task resident in memory.
	/PCB		Lists the contents of each Partition Control Block.
	/POOL		Lists the contents of the system POOL.
	/TASK=name:a:b	Lists the contents of task 'name' between
			virtual addresses  a  and  b.
	/STD		Lists the contents of the System Task Directory
			for all tasks.
3	FUNCTION
	/BL:n		apply to crash-input.  Identifies the starting block
			number of the crash input device. Default=100.
	/EXIT:n		apply to list file.  Terminate analysis after 
			encountering n analysis errors.
	/LIMIT:n	apply to list file.  Terminate listing after n
			pages.
	/MEMSIZ:n	Apply to binary file. Create a binary output file
			4*n blocks long.
	/KMR		Apply to crash input file. Force assignment of
			page address registers.
	/-SP		Apply to list file. Do not SPOOL output.
	/STB		The file is the executive symbol table file.
