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.

Oh it is, by
far. But I love XLAT for 8088-class programming.
I thought XLAT was a real hack!
