How about using Dictionary objects? A dictionary contains key=value pairs, which is similar to an object with named properties.
That's a GOOD question.
I would have suggested that you use the ODT object structures available in TestComplete to create custom classes and objects. That is what I've done in the past with good success. They are deprecating that feature some day (but not yet since there are a lot of people still using it) so I wouldn't recommend going that way.
An alternative (and this is just a mental thought) is to create some sort of generic code in a JScript script extension where you can create an object and add properties to it. That MIGHT work... I've played around with the idea to some success. That way you would call some routine from the extension to create an object with a set of properties (say, pass in an array) and the extension code would return an instance of that object for you to use.
