UTI
L COMMAND
You
can
use
the UTI L command
to
list a directory
of
a tape cartridge
or
to
change
the 5100 operating mode from BASIC
to
communications. You
need
some
space
in the
work
area
in order
to
list a tape cartridge directory.
If
adequate
work
space
is
not
available during execution
of
a UTI L command,
an
error
message
(Appendix
B)
is
displayed. You must then clear the
work
area
(with a LOAOO command,
for
example) and
reissue
a UTI L command
to
continue. Information about
each
file on
the tape cartridge
is
printed
or
displayed on one line per file.
If
you specify a list
to
the printer, all file information
is
printed
without
interruption. You
can
interrupt
the listing
to
either the display
or
printer by
pressing
the
ATTN
key, which will
terminate the command,
or
by pressing HOLD
and
pressing
HOLD
again
to
continue.
The following information
is
printed
or
displayed about
each
file:
• The file number.
• The identification you
assigned
to
the file,
if
any
(see
SA
VE Command).
• File type
(see
File Types).
• The number
of
contiguous 1,024·bytes
areas
of
storage allocated
to
the file.
• The number
of
contiguous 1,024-byte
areas
of
storage unused in the file.
• A number (0-9) indicating the number
of
defective 512-byte
areas
in the file,
or
an
asterisk indicating that the number
is
greater than
9.
This value
can
indicate
when you should relocate a file
into
another file or cartridge
to
avoid
loss
of
data due
to
defective
areas
on the tape.
• The first
and
last statement numbers
for
BASIC
and
SOURCE files.
• Key numbers
saved
in the file
for
KEYS
or
KEY (0-9) files.
