MOVZX             Move With Zero-Extend (386)        Flags: O D I T S Z A P C

MOVZX destination, source

           Logic:        destination .  zero extend(source)

     This instruction copies a source operand to a destination operand and
     zero-extends it. This is particularly useful to preserve signs when
     copying from 8-bit register to a 16-bit one, or a 16-bit register to a
     32-bit one.

     MOVZX is only valid in the 386.
