note sundialsvc4 <p> Even though, sometimes, the value that is the &ldquo;total key to&rdquo; a particular value, suitable for use in a hash-key that singularly leads to <u>one</u> value ... it might be almost-as-well to formulate a hash-key that potentially leads to a <em>list</em> of values, through which (an appropriate accessor-method) will have to search. &nbsp; A well-made accessor makes it easy / invisible. &nbsp; For that matter, you could have several hashrefs and multiple references. &nbsp; Basically, like what you have with the indexes that point into a DB table. </p> 1073836 1073836
