I do not know exactly what ' \: and /: do in K - if I recall
correctly, these are somewhat like rank specifications ("0) ("1 0) and
("0 1) except maybe use _ in place of 1 depending on what you want to
do, and somewhat like the use of each (&.>) and possibly boxing either
the left or right argument.
It might be easier if you expressed the problem you are trying to
solve in English, or if you could point at the relevant K
documentation. I can't find enough on ("m",)'$!4 in documenation I can
find -- stuff like http://www.kx.com/q/d/primer.htm or
http://code.kx.com/wiki/Reference/BangSymbol or
http://code.kx.com/wiki/Reference/DollarSign -- to say anything useful
about that expression.
Thanks,
