× The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.





Several thoughts come to mind.  First, we don't really much care about
efficiency, we care about effectiveness.  Second, we are beginning to accept
the idea that maintenance is where we really lose our efficiencies anyway,
not in the CPU.  Third, flexibility is what we want for our designs.
Flexibility is in the data, not in array manipulation. Fourth, as we move
closer and closer to full searchs and things like EVI we want to be in the
database, not in volatile arrays.

Everything has overhead. But arrays usually have less, depending on the
circumstance, of course.

For example, if you need to retrieve the 100th record of a file, compared
with retrieving the 100th element of an array...

The array is clearly more efficient. ...
