COMMENT	`

[1]    5-Nov-79	If the date/time of the dump is zero, print Unknown
		instead of junk.
[2]    6-Nov-79	If the STOPCD name extracted from the dump is not
		three alphanumeric characters, use SER.  This keeps
		the output filename from being junk.
[3]   13-Nov-79	Add the CBEGIN and CEND commands to allow the user to
		restrict the report to crashes copied (as opposed to
		dumped) between the specified times.
[4]   13-Nov-79	Add a block to each entry containing the disposition
		of the crash.  Add the DISPOSITION command to allow
		a systems programmer to give a disposition for a crash.
[5]   14-Nov-79	Allow the report restriction switches to be placed on
		the REPORT command line in addition to being typed as
		commands.
[6]   18-Nov-79	Change the syntax of the /STRUCTURE command to allow
		the system administrator to specify one or more sets
		of structures to be load balanced across.  Also allow
		the minimum acceptable number of blocks remaining on
		a structure to be specified for each structure.
[7]   19-Nov-79	Change the REPORT format to print the uptime
		immediately after the crash date/time instead of after
		the copy date/time.
[10]  19-Nov-79	Add the /PRIMETIME switch to restrict the report to
		those crashes which occured during prime time
		(0800-1700).
[11]  19-Nov-79	Add the PURGE FILE command which will delete
		SYS:CRASH.SYS but maintain the header so that the
		sequence numbers will continue from the current value.
[12]  26-Nov-79	Add the /UNDISPOSED switch to only report on those
		crashes which have not been disposed
[13]  17-Dec-79	Fix an off-by-one bug in /UNDISPOSED processing which
		caused us to flag some disposed crashes as undisposed.
[14]  28-Dec-79	Read the .EXE directory of the crash being copied and
		only copy the number of blocks specified.  This saves
		disk space when copying crashes dumped onto CRASH.EXE's
		which are bigger that the amount of memory actually dumped.
[15]  18-Mar-80	Add the [NO]DELETE command to allow the user to
		delete the crash file when it is disposed.
[16]  25-Mar-80	Check for -1 in word 30 of the crash and call the output
		file SERnnn if it is.
[17]  25-Mar-80	If the symbol DFTPPN is set to a PPN, don't clear JACCT
		if FILDAE is not running and CRSCPY is running under that
		PPN.  This is for field test sites which do not run FILDAE
		so that DEC can update CRASH.SYS.
[20]  15-May-80	Edit 17 wasn't sufficient for the REPORT command.  Add
		a missing FO.PRV in OPNSYB.
; Revision history continued


[21]  21-May-80	Add the /[NO]HEADER switch/command to enable/disable
		the printing of the headers on the REPORT command.
		The headers are a lose on a slow terminal.  Default is
		still /HEADER.
[22]  21-May-80	Change the /SEQUENCE switch to allow a range of sequence
		numbers.  The new syntax is /SEQUENCE:m:n.
[23]  21-May-80	Change the syntax of the DISPOSITION command to allow
		more flexibility in the disposition of crashes.  The new
		syntax is: DISPOSITION filespec/switches, where filespec
		is a filespec that appears in CRASH.SYS and switches are
		the switches that can be specified on the REPORT command.
		This means that the old syntax of DISPOSITION nn is now
		DISPOSITION/SEQUENCE:nn.
[24]  06-Jun-80	Memorize switches read from SWITCH.INI as sticky defaults
		for typed commands.
[25]  19-Jan-81	Add the MOVE command to move a crash to another
		structure/filespec and update the CRASH.SYS data base.
[26]  16-Jun-81	If any I/O operation fails with status bits returned,
		make sure an error message and the bits get typed.
[27]  24-Jul-81	Preserve the state of the .RBEXT (RH), .RBPRV, .RBVER,
		and .RBSPL words when a crash is MOVEd.
[30]  20-Mar-82	Add a new bit CR.ACT, Crash is Active. This is used in
		conjuction with the CR.DSP (disposed) bit to indicate that
		although disposed, the crash still exists and is being worked
		on. A crash can now be in any of 3 states: new, active, and
		deleted. UNDISPOSED contains new, ACTIVE contains active, and
		INACTIVE contains deleted. The CR.ACT bit is cleared by
		disposing the crash with the /DELETE switch.
[31]  14-jul-82	Make the MOVE command understand /INACTIVE and /ACTIVE,
		and default to /NOINACTIVE instead of /UNDISPOSED so that
		we can move ACTIVE crash dumps around.
[32]   4-Feb-83	Empty S/L before logging out so structures in SSL don't
		get their mount counts messed up.
[33]   2-May-83 Copy crashes in the order of the system dump list.
[34]  15-may-84	Six character stopcodes.
[35]  25-Oct-84	Wait for FILDAE if started on FRCLIN.
[36]  25-Oct-84	Treat device ALL as generic DSK in ALIASD routine to
		allow a CLEAR ALL: command to do the expected thing.
[37]  14-Nov-84	Store ST%RLD and use it to display reloads.
[40]  28-Nov-84	Add /SUMMARY:[ALL!STOPCODES!TOTALS] which will append
		to the end of the REPORT listing a summary by stopcode names
		and the total numbers of crashes, active, undisposed, and
		reload stopcodes.
[41]  28-Dec-84	Defend against holes in the SDL.
[42]  21-Jan-84	Don't include weekends in prime time check.
[43]  23-Jan-84	Eliminate XPN device from CRASH.SYS by copying the FILOP.
		returned filespec to the appropriate places.
[44]   5-Feb-85	System startup is still too slow.  If the file daemon
		isn't running wait the entire .FDTIM seconds before
		proceeding.
[45]   6-Feb-85	Only compare Load number of MONVER.  Customers use
		LH for unrelated things
[46]  15-Aug-85 Do Copyrights.
[47]   3-Oct-85	Teach /STOPCD: to handle wild-carded stopcode name.
		Fix a bug at FIXFI2-1 which can clobber P.
[50]  29-May-86	Fix REPORT command to default to DSK: if any part of a filespec
		was typed, and to go to TTY:CRASH.LOG[-] only if no filespec
		was given.
[51]  29-May-86	Make debugging easier by not getting rid of VMDDT and not
		demanding physical-only SYS:CRASH.SYS when loaded with DDT.
[52]  30-Jun-86	Fix to use SUSET. rather than USETO for Super-I/O.
