My original version was along your lines (that is, no spaces until the
end) except that I couldn't figure out how to insert alternating spaces
in the final result. Thus, I had to insert spaces in sqdata to come
anywhere close to a solution (that is, where output looked similar to
what I was looking for).
I'm familiar with iji, but only with respect to displaying decimal
data. I had never seen your use previously--but that's how this
relative newbie learns J better and better. (And thanks for noticing
that the solution could involve more possible characters than only '.'
and '@'.)
Thanks again to both of you!
