Assemble

Enter assembler code. The syntax is:

a Adress [Opcode]

The first form shows the adress again in the next line where you can enter the opcode.

After a line was entered the next adress is shown one line below. There you can continue with your code:

a c000

a00C000 a9 00 lda #$00

a00C002

NoteRegister size
 

If the 'follow Rep/Sep' is active the size of the akku and indexregisters is adjusted if one of this opcodes is entered. The M and X flags of the processor status are not altered by this.

The default numeric system for all numbers is Hex.
