Fun With Types

Ive had a quick search around, Im sure this must have cropped up before, but couldnt find anything.

I hope I can explain what I'm after, sorry if the words I use arent correct, I never know the 'proper' techy terms for things.

I am trying to return the Pointer to a Type.
Not an individual Field of a particular Type instance, but a means of identifying the instance itself without having to check for matching fields. (Because that has already been done)

As an example, consider:

Type Movies
Field Title$
Field Runtime
End Type

This simple Type would be populated with:

"Star Wars",110 
"Conan The Barbarian",90
"Big Trouble In Little China",87

All good so far, right?
Now, because of the amount of times where I need to iterate through the Type to find the instance I want, I want to put in a function like:

Function GetMovie(Title$)
	For IterateMovies.Movies=Each Movies
		If Iter\Title$=Title$
			Return IterateMovies	
			Exit
		End If
	Next
	Return Null
End Function

The above gives an "Illegal Type conversion" error at the line:

Return IterateMovies

Unsuprisingly because I just used that as an example, but as for what to actually substitute in is what I'm stuck on!

Is there any way to return the Instance itself from a function?
