Hi,
A couple of things could be improved/fixed here: http://www.software-lab.de/doc/refB.html#bin - It should be mentioned that the input can be a list of characters: (bin '("1" "1" "1" "0"))? -> 14 - The result for the example (bin 1234567 4) should be "1 0010 1101 0110 1000 0111"?. I also suggest that there be a "See also" link to 'bin' and 'pad' from the 'format' ref. /Jon
