Best way to put UDG in my program ?

[boriel]

Code:

ASM LD HL, 65368 LD DE, DATA LD B,56 <-- I have 7 characters LOOP: LD A,(DATA) LD (HL),A INC HL INC DE DEC B JR NZ,LOOP DATA: DEFB udg 1 ; <--- LOOK OUT DEFB udg 2 etcc... END ASM

That code is ok... except that once the loop is finished de CPU will run into your DEFB udg 1 and will execute those bytes as if they were assembler instructions.
You should jump somewhere else, RETurn or something.
