    You might need to give a little more context!

    Also enclose program text inside 'CODE' tags (# on 'advanded' window) to keep indentation.

    I'd guess that is a bit of assembler listing output?

    'br -44' is an unconditional jump, offset is from the following instruction.

    Why "-44"? Why don't we use "-48","-40" or "40", "48"

    Thank you!
