The Not command computes the bit-wise logical not of the input returning in terms of a number. All bits that are unset in the input will be set in the output.

Not takes one optional argument, bits=number that specifies the number of bits to be considered in the input. All bits past the specified number are truncated.

Use of this function requires that bits be set, either as an argument to Not or globally via Settings.
