I don't get what your 'offset' field is, but |&.<: might be useful:

   12 | 9+i. 7
9 10 11 0 1 2 3
   12&|&.<: 9+i. 7
9 10 11 12 1 2 3

for a single datum, but I can't see how to do it in one fell swoop for
a whole list of data.

I have specific applications in mind, so the verb needs to look
something like this:  modvalue verb datalist;offset  (although the
modvalue x argument could just as easily be among the y arguments).

A specific example might be:   12  verb  datalist;9
This would return the values in the first paragraph above.

I had been thinking along these lines:

    mm=. modval | (offset + i.(#datalist))
    if. 0 = mm do. mm=. modval end.

But this, of course, does not work.

I would appreciate explicit code only; no tacit expressions.  Much
thanks in advance!
