	I've done precisely this; I have a program of moderate size (~20,000
lines of code, 170K built) that uses multiple document types, and 
as such was an ideal candidate for a rewrite in Object Pascal. There are no
special tricks,  but remember that inheritance is your friend. In some cases
I was able to cut the amount of source in half or even more...

	The program took about two weeks to rewrite, and is much easier to 
debug and maintain, since in many cases there's only one set of UI code
to maintain.
