Painting is a similar pack to the Drawing pack, but obviously is based on the drawing and mixing of colours on the screen. There are many functions, like the Drawing pack.

f0 ... clears the screen
f1 ... lets you choose which of the four available colours you wish to paint.
f2 ... lets you change the actual colours that are available for painting, but you can only have four at the same time to choose from (but these can be any of the sixteen available)
f3 ... decides how the paint will go on the screen and OR makes dark colours go lighter colours when they are painted. XOR makes a new colour appear when the two colours are painted together and gives the impression of the colours mixing. NORMALISE is the way you would expect things to be painted - the first things under, the last things over.
f4 ... enables you to start actually painting with an implement, which in this case is an airbrush which can be any width. As you move the cursor around, a series of random dots appear around your brush. Sounds weak, but it is effective.
f5 ... is a function which lets you pick up a paintbrush which can be any reasonable size and either the shape of a triangle or a square which you can paint with.
f6 ... is the shading function, with which you give a width and a scale factor, and a square of shading appears by your cursor.
f7 ... is similar to the polygon function on the Drawing pack except the polygons are filled.
f8 ... is for text to be used as a shape for painting - so letters can be bounded across the screen.
f9 ... lets you stop painting.

This program could have been adjusted so it goes into Mode 2 for Model B owners and thus create unexpected colours in the XOR painting mode. This has the functions of drawing but has good functions which are applicable to painting. There is again no sound except for prompting, but none is needed really apart from function recognition by note.
