You want to multiply hl by 16? Try doing this:

 add hl,hl  ; multiply by 2
 add hl,hl  ; " by 4...
 add hl,hl  ; " by 8...
 add hl,hl  ; and by 16

There is probably a faster/easier way, but that's how 
I'd do it.

If you want to multiply a point (hl,$0f) by something
-- I'm not sure what you mean -- you could just do two
individual multiplications.
