 The Mount command logically connects devices to Ancillary Control
 Processors (ACPs).  There are three forms of the Mount command,
 depending on the device being mounted.  Note that, if the Mount command
 line is too long to fit on one MCR command line, it may be extended by
 typing a hyphen at the end of all but the last line.

		(must be specified)
	volume-label is the label on the volume (written by the
		INITVOLUME command), 12 characters or less.  Default is

 For more detailed help on a specific keyword, type HELP MOUNT keyword-name
2 ACP
 The format of the ACP keyword is:

 (FTN)	/ACP=taskname

 Where taskname is the name of the Ancillary Control Processor to use
 with the volume.  The default depends upon device type:

	Files-11 disks & DECtapes:	ddnnF1 if it exists
 else	Files-11 disks:			F11ACP
 &	Files-11 DECtape:		DTAACP if it exists
 else	Files-11 DECtape:		F11ACP
	Magtape:			MTAACP
	Network:			NT....
2 DENS
 The format of the DENS keyword is:

 (FT)	/DENS=density

 Acceptable & Default densities depend on the device type:-

	Device Type	Acceptable densities		Default
	===========	====================		=======

	TE16		800 (LOW) or 1600 (HIGH)	800
	TS04		1600				1600
	TU45		800 (LOW) or 1600 (HIGH)	800
	TU77		800 (LOW) or 1600 (HIGH)	800
	RX02		LOW or HIGH			HIGH
2 EXT
 The format of the EXT keyword is:

 (F)	/EXT=block-count

 When a file exhausts its currently allocated space on the volume, it is
 extended by the specified number of blocks.  Default is taken from the
 volume's home block.
2 FOR
 The format of the /FOR keyword is:

 (FT)	/FOR

 This keyword indicates a foreign volume - the format of the volume and/or
 the ACP that controls the volume are not DEC standard.  When mounting a
 foreign volume an ACP name must be specified.
2 FPRO
 The format of the FPRO keyword is:

 (FT)	/FPRO=[system,owner,group,world]

 Default protection for files is set as specified.  The default value of
 the FPRO keyword is taken from the volume's home block for disk volumes,
 and is [RWED,RWED,RWE,R] for tape volumes.  Each subfield
 in the keyword may be one to four letters, taken from {R,W,E,D}.  The
 presence of a code character allows that access for the group of users
 specified by the position of the characters in the keyword value.
2 LRU
 The format of the LRU keyword is:

 (F)	/LRU=FCB-count

 The number of directory File Control Blocks kept in memory by the ACP
 is set to the proper value.  More = faster but more memory.  Default is
 taken from the volume home block.
2 OVR
 The format of the (privileged) OVR keyword is:

 (FT)	/OVR

 If this keyword is present, label processing is suppressed so that a
 volume can be mounted without specifying a label.  The label of a
 volume can be printed by mounting it with the keywords /OVR/VI.
2 OVRFSID
 The format of the OVRFSID keyword is:

 (T)	/OVRFSID

 If this keyword is present, existing file set identifiers are
 overridden.
2 OVREXP
 The format of the OVREXP keyword is:

 (T)	/OVREXP

 If this keyword is present, the expiration date of the volume is
 overridden.
2 PARM
 The format of the PARM keyword is:

 (FT)	/PARM="user parameters"

 The mount command uses this keyword to pass non-standard parameters from
 the command line to a foreign ACP.  The user parameter string can consist
 of up to a maximum of 40 characters enclosed in quotes (").
2 PRTCL
 The format of the PRTCL keyword is:

 (N)	/PRTCL=netqork-protocol

 This keyword allows the user to specify the line protocol to be used by the
 network.  The default is DDCMP.
2 RCK
 The format of the RCK keyword is:

 (N)	/RCK=algorithm-name

 This keyword allows the user to specify the name of a redundancy checking
 algorithm routine.  The default is CRC16.
2 TEL
 The format of the TEL keyword is:

 (N)	/TEL=number

 This keyword allows the user to specify the telephone number of a line to
 be a remote node.  Up to 12 digits may be specified.  The default is null.
2 UIC
 The format of the UIC keyword is:

 (FT)	/UIC=[group,member]

2 UNL
 The format of the UNL keyword is:

 (F)	/UNL

 If this keyword is specified, the volume's index file is unlocked and
 may be written.  Otherwise, the index file is read-only.
2 VI
 The format of the VI keyword is:

 (FT)	/VI

 If this keyword is specified, the volume information for the volume is
 displayed when the mount is completed.
2 WIN
 The format of the WIN keyword is:

 (F)	/WIN=retrieval-pointer-count

 The specified number of mapping pointers is allocated for file access
 windows.  Default:  if I/O optimizations are in system, as large as
 necessary if space is available.  If I/O optimizations were not
 selected during SYSGEN, default is taken from volume's home block.
2 EXAMPLES
 To mount a pack that has a null label on an RK05 drive, selecting no
 special options:

	MOU DK1:

 To mount a magtape volume set at 1600 BPI, overriding expiration dates:

	MOU MM(0,1,3):(PAYROLLVOL1,PAYROLLVOL2,PAYROLLVOL3,PAYROLLVOL4,-
	PAYROLLVOL5,PAYROLLVOL6)/DENS=1600/OVREXP

 To mount an RP06 for use as the main system device (because of heavy
 use we will keep high window and LRU counts):

	MOU DB0:/OVR/VI/LRU=10/WIN=20
