LES loads into two registers the 32-bit pointer variable found in
memory at source. LES stores the segment value (the higher order word
of source) in ES and the offset value (the lower order word of source)
in the destination register. The destination register may be any any
16-bit general register (that is, all registers except segment
registers).
Note: LDS, Load Pointer Using DS, is a comparable
instruction that loads the DS register rather than
the ES register.
