fields.
Batch
mode,
cursor addressing and
full
editing
of
data
are
aimed
primarily
at
form
fill-out.
The form
itself is
composed
of fixed
data, fields,
or
what
we
term
background
data,
and
is
displayed
at
a low
intensity.
Variable, or
foreground
data
is
entered
from
the
keyboard and appears
in
a
bright
intensity.
Foreground
data
may
be edited
and
then
trans-
mitted
to
either
a
computer
or other compatible storage device.
Only
the
foreground
data
is
transmitted
to the
computer.
The
computer or
the
operator
may
then clear
the
foreground
data
from
the
screen
leaving the
background form present
for
further
entries.
The
TAB
key allows
the
operator
to
tab the
cursor
to
the
first
foreground character
of the
next
field.

SETTING UP A
FORMAT
Once
the
screen
is
cleared,
all
character
positions
are
filled
with
foreground spaces.
It
is
therefore
not
necessary
to
write
blanks
in
the
variable entry
fields.
Only
the
form or background
fields
need be generated.
If
the
form
is
to
be
sent
to the
display
from an
external source,
each background
field
must
then
be
addressed
to
its
screen
location
by using
the
cursor address
commands.
The
cursor address sequence
is
lead-in code,
cursor address
code, x-coordinate, y-coordinate.
In
the
following
example,
the
user wished
to
generate a
form
on
a
system
storage device using
the
keyboard
of
the
Hazeltine 2000.
He
intends
to
play
back
this
form from
storage
from time
to
time
and once
retrieved, he intends
to
fill
it
in.
