 
 The Mount command logically connects devices to Ancillary Control
 Processors (ACP's).  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
		12 nulls (no label).

2 KEYWORDS
 In the following list of keywords, each keyword is preceded by a three-
 character code indicating the forms of the Mount command that it is
 legal on.  "F" indicates Files-11, "T" indicates magtape, and "N" is
 used for network keywords.
 
 (FT)   /ACP=taskname           Specifies the ACP to be used.
 (T)    /BYPASS                 Bypasses tape label processor.
 (T)    /DENS=tape-density      Specifies tape density:  800 or 1600.
 (F)    /EXT=block-count        Specifies file extension increment.
 (FT)   /FPRO=[system,owner,group,world]        Specifies default file
				protection for volume.
 (F)    /LRU=FCB-count          Specifies no. of FCBs to keep for speed.
 (T)    /NOLAB                  The tape volume set has no label.
 (FT)   /OVR                    Override label processing.
 (T)    /OVRFSID                Override existing file set identifiers.
 (T)    /OVREXP                 Override expiration date.
 (FT)   /UIC=[uic]              Specify UIC volume is mounted under.
 (F)    /UNL                    Unlock volume index file.
 (FT)   /VI                     Display volume information on the TTY.
 (F)    /WIN=retrieval-pointer-count    Specify number of mapping ptrs
				to be allocated for file windows.

	HELP MOUNT KEYWORDS keyword-name
3 ACP
 The format of the ACP keyword is:
 
 (FT)   /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 except DECtape:        F11ACP
	DECtape:                        DTAACP
	Magtape:                        MTAACP
3 BYPASS
 The format of the BYPASS keyword is:
 
 (T)    /BYPASS
 
  Tape label processing on the volumes mounted is bypassed.
3 DENS
 The format of the DENS keyword is:
 
 (T)    /DENS=density
 
 Where density is either 800 or 1600.  The tape density is set to either
 800 BPI NRZI, or 1600 BPI Phase Encoded.  Default is 800 BPI NRZI.
3 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.
3 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.  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.
3 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
 /LRU=3.
3 NOLAB
 The format of the NOLAB keyword is:
 
 (T)    /NOLAB
 
 If this keyword is present, the tape volume set does not have a label.
3 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.
3 OVRFSID
 The format of the OVRFSID keyword is:
 
 (T)    /OVRFSID
 
 If this keyword is present, existing file set identifiers are
 overridden.
3 OVREXP
 The format of the OVREXP keyword is:
 
 (T)    /OVREXP
 
 If this keyword is present, the expiration date of the volume is
 overridden.
3 UIC
 The format of the UIC keyword is:
 
 (FT)   /UIC=[group,member]
 
3 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.
3 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.
3 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
