NOT AND INSTRUCTION ?

[StephenG1CMZ]

Thanks for that suggestion Chromos.
If it is NAND that is wanted I would suggest:

Code:


EXPORT NAND(LST)
BEGIN
 IF SIZE(LST)==1 THEN
  RETURN (LST(1)==0);
 END;
 RETURN NOT (ΠLIST(LST));
END;

That has the advantage of also working with a single input, which the built-in list function does not handle.
