I stand by this statement, Scott.. this accomplishes precisely what LES BX, 
THIS accomplishes.
Well, OK, if you really must preserve AX, then embed the above within a PUSH 
AX/POP AX pair :)

That is, LEA loads a NEAR pointer, and LES loads a FAR pointer.. ummm, but if 
you read back what I said, I said that after LES BX, THIS, ES:BX contains a 
pointer to THIS.
Ummm, I think that is the same thing as what you said, yes?

I do believe you are right.. and on a 386+, also LFS and LGS.

One certainly hopes so :)
