Hi,I would like to use a function that takes a list, such as msum, andinstead apply it to each item of data as it arrives, essentiallyconverting a batch process into an online process. In some otherfunctional languages, it is possible to perform lazy evaluation of afunction on a list. Searching through code.kx.com brings no mentionof such a thing, so I thought next, it might be possible to save thestate of a function on each invocation (when iterating using / or ,for example).Is it possible to convert a batch function into an online functionwithout rewriting?Thanks in advance,Victor

no, you have to do it yourself by hand
