The Main Menu has eight options available and these are as follows:
Select Graphics Mode
The Graphics Mode selected will define the size of each addressable element in a shape. Mode 3 has larger elements and therefore less definition than Mode 4, but it has the advantage of being able to use four colours. If Mode 4 is chosen, the number of colours is reduced to two. The program starts in Mode 3.
Select Colour Set
There is an interdependency between the colours available and the graphics mode specified. Colours available for each combination are shown in Fig 3.
MODE 3 MODE 4 SET 0 Green (1)
SET 1 Buff (1)
The number in brackets indicates the key to be used to select this colour.
The program starts using Colour set 0.
View Character Sets
This option enables the user to look at the current state of any set of shapes, and after viewing enables any other set to be used until the # key is pressed.
Set Working Graphics
There are three graphics pages holding shapes that can be edited. In this option you can select the page you wish to use. The program starts using page 6.
Set Background Colour
When it is intended to create a new character or graphics set, the first thing to do is to choose a page and select a colour for it. This is done using this option.
The keys for each colour are shown under 'Select Colour Set' above.
Set Character Grid Size
In the editor it is possible to vary the size of the shape being edited. Choose the number of rows and columns for each shape. The editor then splits the page into grids of the size you have chosen. The program starts with a grid size of 8 rows x 6 columns.
Copy or Move Characters
It is possible, if required, to copy a shape being edited to another position. It is important to remember when doing this that the size of the area being transferred is the drig size chosen easlier and so, if it is required to transfer a different sized area the grid size must be changed first.
Having set the various parameters described above it only remains to actually edit the shape of the characters or graphics. The editor will ask which character number is required and this will depend on the grid size. On selection, the program shows the page being edited across thebottom of the screen and a large version of the current grid above this. One square, the cursor, is flashing and can be moved around the grid, using the four arrowed keys on the left and right of the keyboard. the colour of the flashing cursor can be changed by using the keys 1-4 or 0, 1 if in a two-colour mode only.
The colours corresponding to each key are shown under 'Select Colour Set' above. A square is painted by pressing ENTER. If a square is the wrong colour than it is simply necessary to repaint it.
