Hi Andriy,

Initially i started with a macro for the complete routine, but later as types
started to play important role in it, i have to split it to routines.

I thought of this idea to do prop check in a macro, but then i thought
it might cover a bigger range of files and so thought of doing that separately.
For, simplicity left it this time.
