Enter a SQL statement to edit the current picture. This should be a
UPDATE statement which updates the column called "C" of the table called
"GRAPH". It has columns "X" and "Y" which are the coordinates of the
pixel, and "C" which is the colour of the pixel. It may also be a SELECT
statement in order to query it, and the response is then displayed
(which must be a single row and single column only).
` or =
Exchange the current picture with the spare page. (The spare page is not
stored in the puzzle set; it is lost when Free Hero Mesh is terminated.)
Click in the colour palette on the right to select a colour. With the left
button, that colour is selected as the current colour. The middle button
will replace everything of the current colour with the clicked colour, and
the right button will exchange pixels between the current colour and the
clicked colour; in either case, if any block is marked, only the marked
block will be affected.
