CREATE-DIRECTORY

@CREATE-DIRECTORY <directory name>, <device name>, [<unit>], [<'F' or 'R'>], <subunit>, <bit file address>

Create a new directory on a device. The old directory is destroyed and all files are lost.

<directory name>: the name which will be written onto the new directory. A maximum of 16 alphanumeric characters, including the character, are legal.
<device name>: the name of the mass storage device controller on which the device unit is connected. See Norsk Data Document ND–60.128.01 SINTRAN III REFERENCE MANUAL Appendix F for legal names.
<unit>: the unit number. Only to be specified if SINTRAN III is generated with multiple units. Unit number starts at 0 (zero) octal, default is 0 (zero).
<'F' or 'R'>: F = a fixed cartridge disk pack. R = a removable cartridge disk pack. Otherwise, the parameter is not used.
<subunit>: applies only to big cartridge disk.
<bit file address>: may be specified if the user wants to place the bit file in a specific area on the medium. The bit file is used to contain a free / reserved map of the pages on the device medium. Unit is page offset in octal. Default = the file system will select a medium dependent optimal value. Note that for system disks a number of contiguous files must be placed in a certain order, from page 0, and the bitfile should be placed in the middle of the remaining area. For non-system disks and floppy disks the default can be used. (The System Supervisor manual contains more information on this parameter).

Rules:

Permitted only for user SYSTEM when disk, for all users when floppy disk.
Fixed or removable is specified only for 10MB cartridge disks.
if SINTRAN is configured with only one unit (number 0), the <unit> parameter must be omitted (together with the comma).

Example:

@CREATE-DIRECTORY PACK-ONE, DI-1-1, 1, F

A directory named PACK-ONE is created on cartridge disk controller 1, unit 1, fixed pack.
