number = layer?

[Paul Dupuis]

Here is a basic question I am not sure of (after decades of LC coding) 
and can't pin down in teh Dictionary

If you execute "put the selectedChunk into X" then (assume a valid 
selection) X contains an expression of the form "char <start> to <end> 
of field <fieldNumber>"

If I want to check that the selection is in one of a number of fields on 
my stack, say called "Address", is the following conditional correct?

if word 7 of X = the layer of fld "Address" then -- the selection is in 
the address field

In other words, is the <fieldNumber> returned by selectedChunk the same 
as the layer property of objects OR is it an index to the number of 
fields on that card (two different things if you have objects other than 
fields on the card)

Any one know for sure?
