HP 250 - Assigning Names to Storage Media (PRINT LABEL); Physical Addresses

System Commands
Accessing mass storage devices is very similar to this. You can
access a file on any particular storage device by knowing either
the label of the storage medium (the volume name) or by knowing
the physical address of the storage device (the unit specifier).
Assigning Names to Storage Media (PRINT LABEL)
You assign names to storage media with the PRINT LABFL command.
For example, if you wanted to have the label SAMPLE on the volume
in the default mass storage device, you would enter:
PR INT LABEL "S(..)MPLE tt
The label you give to a volume cannot exceed 8 alphanumeric
characters, the first of which cannot be a number.
If you do not know the label on the default mass storage device,
but wish to find out, enter the following command:
Physical Addresses
Each storage device is assigned an address by which you can
access the files located on the medium that is currently located
in the drive.
For example if you want to print the label SAMPLE on a tape
cartridge (which is not the default mass storage device), you
enter the following command:
PR INT LABEL nSAMPLF If ON tt: I( If
Th e": K" s p e c i fie s the ph y sic a 1 add res s ( the un its p e c i fie r ) 0 f
the tape.
If you wanted to determine the label on a tape currently in the
tape drive (and the tape drive is not currently the default
device), you enter the following command:
I:~E(~:O I ... ABEL (~I$ DN ": 1< II
A list of all physical unit specifiers appear in Appendix C.
Once you understand this concept of accessing discs and files
through either physical addresses or volume names, you will have
no trouble using the commands presented in this chapter.
