OPERATION
NOTE
If
lines
per
page
is 24, the row
number
is the
same
as the
line
number
(cursor location).
In all
other instances,
it is
necessary
to
count
in
order
to
determine
the
(decimal) number
of a
row.
NOTE
further
Once
a
scrolling
region
is
defined, cursor location
is
determined
by the
scroll region. E.g.,
the
first
line
of the
scroll region
is
identified
as
line
1,
the
second
line
(if
any)
as
line
2, and so on.
NOTE
finally
Data
exceeding
the
last line
of the
scrolling
region pushes
all
preceeding
lines
of the
region
up
one,
so
that
the
first
line
of
data
in the
region
is tost.
