	invoke ux, cl, dh, bx, bp	;ax can't be used ( register value overwritten... )
	.186
	invoke ux, cl, dh, bx, ax
	.386
	invoke ux, cl, dh, bx, ax

;--- it doesn't matter whether the target are signed values, it's always zero-extended!

	.186
	invoke sx, cl, dh, bx, ax
	.386
	invoke sx, cl, dh, bx, ax

;--- with type coercion, the values are sign-extended!
;--- if cpu < 386, registers dl, dh and dx cannot be used as arguments 
;--- because they're overwritten ( Masm won't detect this!)
