Rudy,

"Sand" took me by surprise.

How about this.  The left hand number is not a number, its an S, for 
"slab".  Thus one also finds PS, for Porch Slab, and B stands for Beam. 
  The number on the right indicates which slab design it is.

Now all I have to do is figure out where the slab design details have 
gone.

Thanks.
