Add the Javascript plugin and use Javascript example:

function TwosComplement8Bit(dec)
{
  return ((dec >>> 0) & 0xff);

EZB.SetVar("$neg128", TwosComplement8Bit(-128));
EZB.SetVar("$neg127", TwosComplement8Bit(-127));
EZB.SetVar("$neg64", TwosComplement8Bit(-64));
EZB.SetVar("$neg1", TwosComplement8Bit(-1));

Run the script, then you can confirm the above EZ-Scripts variables:
