The Nor command computes the bit-wise logical nor of the inputs returning in terms of a number. All bits that are unset in both inputs will be set in the output.

Nor 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 Nor or globally via Settings.
