Comparing a substring to a substring

[Chris Sharman]

Do you mean a specific substring ?

if 0< index(dataitemB, dataitemA[start:len]) ??

Otherwise, if the question is "what's the largest substring of A also found
in B" then that's quite a nasty order n-cubed problem, I think, and you'll
need to simplify it, or do it in a 3gl.

I need to determine whether a substring in data item A exists as a
substring in data item B. I am familiar with:

IF 0 < INDEX (data item B, substring)

Thanks.
