Re: onOff question

Hi Tomas, All functions ignore atomic CDRs of the last argument cell. You could also try (onOff A B . X), the 'X' will be simply ignored. so why is not NIL in the (onOff . NIL) ignored? ;-) Well, the NIL _is_ ignored, in the same sense as the 'X' is ignored. The NIL you observe results

Re: onOff question

Hi Tomas, Yes. But on the other hand, missing arguments usually default to NIL in picoLisp. Makes not much sense in the case of 'onOff'. I know, but it still doesn't make sense even in v2.3.7. That's not what I mean, it has nothing to do with the version. : (onOff) is the same as
