<h4 class="section">VAX Operands</h4>



   <p>The immediate character is <code>$</code> for Unix compatibility, not

<code>#</code> as DEC writes it.



   <p>The indirect character is <code>*</code> for Unix compatibility, not

<code>@</code> as DEC writes it.



   <p>The displacement sizing character is <code>`</code> (an accent grave) for

Unix compatibility, not <code>^</code> as DEC writes it.  The letter

preceding <code>`</code> may have either case.  <code>G</code> is not

understood, but all other letters (<code>b i l s w</code>) are understood.



   <p>Register names understood are <code>r0 r1 r2 ... r15 ap fp sp

pc</code>.  Upper and lower case letters are equivalent.



   <p>For instance

<pre class="smallexample">     tstb *w`$4(r5)

     </pre>



   <p>Any expression is permitted in an operand.  Operands are comma

separated.
