It's a 1-byte instruction that replaces AL with its index in a 256-byte table 
stored in DS:BX and does so in 11 cycles!  What's not to like?  The closest 
equivalent would be MOV AL,[BX+SI] which is 3 bytes long, takes 15 cycles, and 
burns up SI in the process.

Today, don't use it.  But on 8088, it's just plain *fun* to use.
