DASM Question.

[JohnnyRockets]

Hi,

 

Will DASM automatically generate code for the 6507/6502 processor, or does one have to tell it what type of processor is the "target"?

 

 

Thanks,

I was always able to assemble the example code from this forum with

dasm -f3 source.asm -otarget.bin

So the answer should be "no, but be sure to include the '-f3' option.

(I patched my dasm, so this is the default, though.)

DASM can compile source for a number of different CPUs. If you don't tell it the type of CPU you'll end up with errors like this:

error: Unknown Mnemonic 'sty'
error: Unknown Mnemonic 'lda'
error: Unknown Mnemonic 'nop'
...

 

The way you tell it the type of CPU is by the processor pseudo-op:

		PROCESSOR 6502

 

 

Put it as the very first line of your source code. It must have whitespace before processor. If you do this:

PROCESSOR 6502

 

you'll get an error:

error: Unknown Mnemonic '6502'.
