Is there a way to derive the x and y (width and height) of text objects ? I
would like to know the complete string dimensions.

I am trying to center text on an object and knowing it's width would make
the job easier

Yes by using max_extent(OBJECT_IDENTIFIER) and min_extent(OBJECT_IDENTIFIER). It works
with any object.
#declare you text object with no rotation, feed it to max_ and min_extent, calculate
the mid point 
and translate your object as needed. If you need to rotate it, translate it by half
it's dimention 
(to center it around the origin), rotate, then translate to it's final position.
