 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 furthur HELP with CDA type:
 
		      HELP CDA keyword
 
     where keyword is one of the following:
 
	Commandline      The CDA commandline and its use.
	Report           CDA report selection switches.
	Function         CDA function control switches
 
 
2       COMMANDLINE
 
 
			  CDA Command Line
 
    Since we only dump to magtape, the command line is
 
      [listfile/sw],[binary file/sw]=symbol file/STB,crash-input[/sw]
 
    where:
 
      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       REPORT
 
			  CDA Report Switches
 
 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.
 
2       FUNCTION
 
			  CDA Function Switches
 
	/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.
