The general form of the Initialize Volume command is: INI[TVOLUME] ddnn:["]volume-label["][/keyword(s)] where: ddnn is the device name and unit number of the volume to be initialized. If there are too many options to fit on one command line, the line may be continued by ending each line except the last with a hyphen ("-"). The volume on the specified device is initialized with the given label. Keywords may be specified to control the parameters that the volume is initialized with. The following keywords are available to the INITVOLUME command: /ACCESS="character" Specify access protection /BAD=[option] Select bad-block processing /DENS=density Select magtape/Check floppy disk density /EXT=block-count Specify file-extension increment /FPRO=[s,o,g,w] Specify default file protection for vol. /INDX=index-file-position Specify position of index file /INF=index-size Specify initial size of index file /LRU=directory-count Specify directory count /MXF=file-count Specify maximum no. of files on volume /OWNER=[group,member] Specify owner of volume /PRO=[s,o,g,w] Specify volume protection /UIC=[group,member] Specify owner of volume /WIN=retrieval-pointer-count Specify number of file windows /VI List above options and current values for volume on terminal.

Legal values for "character" are the uppercase letters A through Z, the digits 0 through 9, and the following special characters: ! " % & ' ( ) * + , - . / : < = > ? ; The default value for "character" is a space. 2 BAD The legal formats of the /BAD keyword are: /BAD=[MAN] Accept bad block list from terminal /BAD=[AUTO] Read bad-block file created by BAD /BAD=[AUTO,MAN] Read bad-block file, accept blocks specified from the terminal. /BAD=[OVR] Include the last track in the BADBLK.SYS file. /BAD=[OVR,MAN] Override the manafacture's bad-block descriptor file and accept blocks specified from the terminal. The default is /BAD=[AUTO]. 2 DENS The legal formats of the DENS option are: /DENS=800 Select 800 BPI density. /DENS=1600 Select 1600 BPI density. /DENS=6250 Select 6250 BPI density. /DENS=LOW Select lower of two possible densities. /DENS=HIGH Select higher of two possible densities. /DENS sets the bit density of a magnetic tape loaded on a TE16, TU16, TU45, TS11, TU77, or TU78 tape drive. The default is device-dependent. For a full list, type HELP INI DEFAULTS DENS 2 EXT The format of the /EXT keyword is: /EXT=block-count /EXT specifies the number of blocks by which a file is to be extended when the file has used all of its allocated space. Legal values for block-count range from 1 through 255(10). The default is /EXT=5. 2 FPRO The format of the /FPRO keyword is: /FPRO=[system,owner,group,world] The default protecton for all files created on the volume is set to the specified value. Each of the four fields can contain one or more of the following characters, in the order listed: R To allow read access to the specified group of users. W To allow write access to the specified group of users. E To allow extend access to the specified group of users. D To allow delete access to the specified group of users. Default: /FPRO=[RWED,RWED,RWED,R] 2 INDX The format of the /INDX keyword is: /INDX=index-file-position /INDX specifies the logical block number for the index file. The keyword can be used to force the index file, the MFD, and the storage allocation file to a specific volume position, usually to minimize access time. Legal values for index-file-position are: BEG Place index file at the beginning of the volume. END Place index file at the end of the volume. MID Place index file in the middle of the volume. BLK:nnn Place index file beginning at the specified block number. The default is device-dependent. For a full list, type HELP INI DEFAULTS INDX 2 INF The format of the /INF keyword is: /INF=initial-index-file-size /INF specifies the number of file headers to allocate initially in the index file. The default is device-dependent. For a full list, type HELP INI DEFAULTS INF 2 LRU The format of the /LRU keyword is: /LRU=directory-count /LRU specifies the approximate number of directories that will be accessed simultaneously. The legal values for the directory-count range is 0 through 127(10). The default is /LRU=3. 2 MXF The format of the /MXF keyword is: /MXF=file-count /MXF specifies the maximum number of files allowed on the disk volume. This number corresponds to the number of file headers in the volume's index file. The maximum legal file-count is device-dependent and can be found by typing HELP INI KEYWORDS MXF MAXIMUM. The default is device-dependent. For a full list, type HELP INI DEFAULTS MXF 2 OWNER The formats of the /OWNER keyword are: /OWNER=[g,m] (disks, DECtapes, and magnetic tapes) or /OWNER="owner" (magnetic tapes only) /OWNER specifies the owner of the volume. It is similar to /UIC, but for magnetic tapes allows you to use a syntax other than [g,m]. 2 PRO The format of the /PRO keyword is: /PRO=[system,owner,group,world] The specified volume access rights are extended to the specified groups of users. Each field (system, owner, etc.) controls one group of users and contains one or more of the characters given below, in the order given below: R Allow read access W Allow write access C Allow create access D Allow delete access The default is: /PRO=[RWCD,RWCD,RWCD,RWCD] 2 UIC The format of the /UIC keyword is: /UIC=[group,member] /UIC specifies the owner of the volume. Legal group and member numbers range from 1 through 377(8). The default is: /UIC=[1,1] 2 WIN The format of the /WIN keyword is: /WIN=retrieval-pointer-count /WIN specifies the number of mapping pointers to be allocated for file windows. The retrieval-pointer-count must be 1 through 127(10). The default is: /WIN=7. 2 VI The format of the /VI keyword is: /VI /VI lists all of the INI keywords and their values for the specified volume. You must use at least one other keyword with /VI.
