I have need for a verb like residue | but which returns the mod value instead of 0. For example, instead of 9 10 11 0 1 2 3 4... for a mod value of 12, it will return 9 10 11 12 1 2 3 4.... I can do it easily 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!
