Symbol After - AMSTRAD cpc 6128 User Instruction

Note that the value of 0 appearing in the 2 final parameters means that you need
only type in:
SYMBOL 255,1,3,7,15,31,63
Note that you can enter the parameters in binary to save you converting the 'pattern'
of the symbol that you've created into decimal form. (Remember to use the & X binary
prefix.) For example:
SYMBOL 255,&X00000001,&X00000011,&X00000111,
&X00001111,&X00011111,&X00111111
.... Now, to see the character:
PRINT CHR$(255)
Assigning the above parameters to a typeable character on the keyboard would result
in the new character appearing whenever the appropriate key is pressed, or wherever
the previous character would have been printed. Furthermore, BASIC will not reject
this new character as incomprehensible, but will regard it as the equivalent of the
previous character.
Further information concerning user-defined characters will be found in part 2 of the
chapter entitled 'At your leisure .... '.
