Type: External (3.0 and later)
Syntax:
LABEL [d:][volume label]
Purpose: Creates or changes or deletes a volume label for a
disk.
Discussion
A volume label may consist of up to eleven characters (the same
characters that
are legal for a file name). If you enter an erroneous volume label, the
error
message Invalid volume label appears, and the system prompts for a
re-entry.
If you use this command without entering a volume label, the program
displays
Input volume label - Up to 11 characters.
Press ENTER only to delete label.
Enter a volume label, or press the Enter key to delete the current volume
label.
To display the current label, use either the DIR or VOL command.
Example
To create the label TESTVOL1-A on the diskette in drive B, enter
label b:testvol1-a
