It's meant to be used interactively via the Python REPL as well as programmatically. I might implement a specific ASM REPL at some point. It's meant to be used interactively via the Python REPL as well as programmatically. I might implement a specific ASM REPL at some point.
An example: An example of a Python REPL session:
>>> from dcpu_16 import CPU
>>> c = CPU(debug=True)
>>> c.load_m() # loads demo program
>>> c.step() # step by one instruction
<< SET
<< c.r[0x0]

>>> c.pc = 0xA # jump to 'loopy thing'
>>> c.step()
