Information Block Format

FIELD   SIZE    VALUE
======================
id      DB      'BBFS'
clean   DB      0 = clean, 1 = unclean
next    DD      1

file    DB      '12 bytes    '
size    DD      #blocks

file    DB      '12 bytes    '
size    DD      #blocks

file    DB      '12 bytes    '
size    DD      #blocks


Up to 36 files per IB



Or this format:

FIELD   SIZE    VALUE
======================
id      DB      'BBFS'
clean   DB      0 = clean, 1 = unclean
next    DD      1

fn_len  DB      bytes in filename
file    DB      'name'
size    DD      #blocks

fn_len  DB      bytes in filename
file    DB      'name'
size    DD      #blocks

fn_len  DB      bytes in filename
file    DB      'name'
size    DD      #blocks

The second is more "Forth-like" IMO, but the first may be simpler in the
end.
