Hi,
I'm beginning to code in 6502 assembler. I'm using the build in monitor program to test my knowledge.
Here is one of my program:
My first problem is, to execute the code, I must alway go out the monitor ( with 'x') and type "sys dec("0c00")". If I try "g 0c00" or "j 0c00" inside the monitor, nothing happen.
Is it a problem with my code?
Ben
