Re: Array Data Structure

That's right. %LOOKUP may eventually support lookups in array data structures, if we can come up with a good syntax for specifying a subfield to use as the lookup key.

For now, you can use a FOR loop to search for things. Or, if your data is in sorted order, you could use the C run-time function "bsearch()".
