The command that formats a diskette is called the HEADER com
mand. It has a long form and a short form. To format a blank (new)
disk, you MUST use the long form as follows:
HEADER "diskname", li.d.[,Ddrive number] [<ON|,>U device numt
After the word HEADER, you type a name of your choice for the disk,
within quotes. You can choose any name with up to 16 characters.
You should choose disk names that help you identify what will be
stored on the disk.
Follow the diskname with a comma and the letter "I". Now a two
character i.d., followed by a comma. Your disk i.d. does not have to
be numbers; you can also choose letters. You may want to develop a
consecutive coding system for your disks, such as A1, A2, B1, B2.
If you have no additional diskdrives, just press RETURN at this point
since the Commodore 128 automatically assumes the drive number
is 0 and the device number is 8. You can specify these parameters if
you have more than one drive or a dual drive.
The next parameter in the command selects the drive number. Press
the "D" key and if you have no additional disk drives, press the zero
key followed by a comma. Dual drives are labeled 0 and 1. The
device number parameter starts with the letter U so press the "IT
key followed by the preassigned device number for a Commodore
disk drive which is 8.
Here is an example of the long form of the HEADER command:
HEADER"RECS",IA1,D0,U8 nmPHH
This command formats the diskette, calling the directory RECS, the
i.d. number A1, on drive 0, unit 8.
The default values for disk drive (0) and device number (8) will be
used if none are supplied. This is an acceptable long form of the
HEADER command:
HEADER "MYDISK", 123 I
The HEADER command can also be used to erase all data from a
used disk, so the disk can be reused as if it were a brand new disk.
Be careful that you don't erase a disk that contains data you may
want someday.
