<title>Instruction : shift-r</title>
<h1>shift-r</h1>
This instruction reads in the contents of the <a href="help.Nop-Register-Notation.html">?BX?</a> register, and shifts all of the bits in that register to the right by one. In effect, it divides the value stored in the register by two, rounding down.
