[Orange |Green ]PxlOn <row>, <col>
Colours the pixel at row <row> from the top, column <col>
from the left. If either Orange or Green are
specified, the pixel will become that colour, otherwise it will be
This is one of the Pxl... commands, which act directly on the
graphics screen, rather than plotting a point relative to the current
axes. If the standard range ('Range 1, 127, 0, 1, 63, 0') is
being used, the same pixel could also be coloured using the command
'Plot <col>, 64-<row>'. Notice that the
horizontal and vertical co-ordinates are referred to in the opposite
order, and that the vertical co-ordinate is measured in the opposite
direction. Using the range 'Range 1, 127, 0, 63, 1, 0' will
give axes which are measured from the top down so that it is only
necessary to swap the order of the co-ordinates when changing between
axes-based and screen-based commands.
Unlike the Plot command, this command cannot be followed by a
display triangle (_) to allow direct pixel editing.
