RE: Our OO Verus Procdedural Discussions and New Forum

This is just a point of curiosity on my part.  What category would the
following scenario fall under,inheretance, extension?  Can anyone give
me an example of how this would be accomplished in OO and/or procedural?

You have an object called a fitzle.  It has three properties.  1. It can
hold data.  2. It can have data written to it.  3. It can have its data
read.

You want to use this fitzle object in several ways but you need a few
additional properties for each.  First, you want it to be usable for
displaying data.  You also want to use it to format data being printed.
Thirdly, you want to organize data in this fitzle object in a particular
sequence.

So for all three you feel you need to add the properties "type of file",
"device type", "record format".

You now want to differentiate these fitzle objects further.  To the
fitzle object you will use for displays you add the properties "display
type" and "maximum devices".  For the fitzle object you use for printing
you add the properties "page size", "lines per inch", and "characters
per inch".  For the one being used to organize data you add "key field".
"key field" has the properties "sequence" and "data type".
