Cassette and Disk Storage with the Apple lie 193
using the following configuration :
Vx
where x can be any integer from 1 to 254 .
If we wished to initialize a diskette in drive 2 attached to the
controller slot 4 using the name "BEGIN" for the greetings*
program, we could do so by issuing the following command :
** INIT BEGIN, 54 , D2, V100
This command would assign the diskette a volume number of
100 . The volume number cannot be changed unless the diskette
is reinitialized.
Again,
the order of the disk, slot, and volume specifications is not
important. If a volume specification is not indicated , the diskette
will be assigned a volume number of 254.
If the volume number is specified with a DOS command , DOS
will check the diskette's volume number to be sure that it
corresponds with the volume number indicated with the DOS
command's V parameter. If you inadvertently specify the wrong
volume number or insert the wrong diskette, the following error
message will be displayed:
VOLUME MISMATCH
The use of the volume specification can prevent a diskette from
accidentally being O':'erwritten.
The DOS CATALOG
command ignores the volume specification.
The
volume number is displayed in the catalog listing.
*
**
This program is run when the diskette is booted.
INIT will be discussed in detail later in this chapter.
