OTHER SYSTEM FUNCTIONS
27.4 -- Diskette File Functions
Ail
of
the Tunctions described in this section require a
t~enty-Tive
byte
parameter
table
called the diskette file
table,
o~
OFT.
The format of the table is shown here so that
it
will
not have to be repeated ror each function.
It will
be seen that the first sixteen b'ytes
of
the
DFT
are
identical
in format
with
an
MDOS d
ir-ectory entry.
Also,
the entire DFT
is
or
the same
format as
part
of
an
IOCB
(starting
with
IOCLUN
and
ending
with
lOeSBE).
The
contents
of
the
individual fields are not described
in
this
section
since
they
have
been
adequately discussed in sections 24.1.4 and
25.3.1.
All of the diskette rile functions
~ill
change
the
diskette controller variables below location $0020.
