Re: Howto try small machine code programs in BASIC ?

The CC register is 8-bit. The correct code should be as follows.

Code: Select all

TFR CC,A
STA $5002

LDA $5000 ' Load A from Memory
ADDA #1   ' A=A+1
STA $5000 ' Store A to Memory
TFR CC,B  ' Transfer value of CC to B register
STD $5002 ' Store D (A+B register = D register) to Memory

EDIT: Holding down Shift+7 (') does not work correctly even without the translation. EDIT: The backsla...
