POINT
will
return a number between 0-255.
If
0
is
returned, then there
are
not
any dots turned on in the specified
column.
If
255 (or 127)
is
returned, all
of
the dots in the specified column
are
turned on. 255
will
be
returned
if
you specified GPRINT 255 or FF and 127
will
be
returned
if
you specified GPRINT 127 or 7F.
The number the
PC-2
returns
will
identify
the
dot
pattern specified
with
GPR
INT. For instance,
if
your
program
uses
GCURSOR 100 and you specified GPRINT
8,
the
PC-2
will
return the value
of
8 when you enter POINT 100.
For details on specifying
dot
patterns,
see
GPR
INT.
Example
The following program randomly moves the GCURSOR position among the first 10 columns.
It
GPRINTs pattern
8
(a
single dot). The program then tests whatever column you specified
and
tells you whether
or
not
a
dot
is
on
in the column.
