HEADER
HEADER "diskname" ,Ddrlve# Ladd/ILION Uunitifj
Before you can use a new diskette for the first time you must formal it
with the HEADER command. If you want to erase an entire diskette for
re-use you can use the HEADER command. This command divides the
disk into sections called blocks, and it creates a table of contents,
caned a directory or catalog, on the disk. The diskname can be any
name up to 16 characters long. The i.d. number is any 2 characters.
Give each disk a unique i.d. number. Be careful when you HEADER a
disk because the HEADER command erases all stored data. Giving no
i.d. number al;ows you to perform a quick header. The old i.d. number
Is used You can only use the quick header method If the disk was
previously formatted, since the quick header only clears out the
directory rather than formatting the disk.
