20 CHARACTER SETS

The program offers 20 Character Sets which can be viewed, saved and place into your own programs with the minimum of fuss.

To load, either type LOAD "": - press [ENTER] or select the loader option on 128K machines.  An arrow will appear on the screen.  To control it, use the following keys:

	KEY:	EFFECT:

	Q	UP
	A	DOWN
	O	LEFT
	P	RIGHT
	M	SELECT

There will also be twenty different sets of the letters 'abcd' and the words "SAVE" and "QUIT" printed on the screen.  Moving the arrow over any of these will highlight the letters.  Pressing 'M' while the letters are highlighted will make the selection and result in one of the following:

a)  If any of the letters 'abcd' are selected the screen will clear and that complete set will be displayed.  The computer will wait for a key press before returning to the menu.

b)  If the "SAVE" option is selected the computer will save the current character set to tape.  If no set has been selected before trying to save the computer will return to the menu.

c)  If the "QUIT" option is selected the computer will ask the question "Are you sure?".  Select "Y" and the machine will reset.  Any other answer will return you to the menu.

After having saved a particular character set to tape, follow the instructions below to use it in your own programs:

1.  Choose a suitable memory location for your set, bearing in mind it is 768 bytes long.  e.g 60000 ; x

2.  Clear 1 less than your chosen address.  i.e. CLEAR 59999

3.  Load the saved character set into your chosen address.  i.e. LOAD "" CODE 60000,768

4.  Enter the following into your computer:
    POKE 23606,x-256*INT (60000/256) : POKE 23607,INT (x/256)-1
    i.e. for our example:  POKE 23606,60000-256*INT (60000/256): POKE 23607,INT (60000/256)-1

The default address for the character set is 64768 (POKE 23606,0 : POKE 23607,252).

Once the code has been loaded and the POKEs executed the computer will use the new character set.  Return to the normal set by POKEing 23606,0 and 23607,60.  Use "TILT CHR$ SET") (CHR$=EXTEND MODE U) as the filename to load any of the sets into Gifsofts Professional Adventure Writer.

	LOAD "" CODE 60000,768
	POKE 23606,60000-256*INT (60000/256): POKE 23607,INT (60000/256)-1
