String concatenation:

document.getElementById('input2').value = "stuff" + document.getElementById('input1').value + "other stuff";

When dealing with numbers you could start by concatenating with empty string to avoid adding numbers together instead of concatenating to strings (because of operator evaluation order):

document.getElementById('input2').value = "" + 1234 + 567 + document.getElementById('input1').value + 89;

Why don't you try something in jQuery?

  $("#Anything").click(function() {
     $("#Field1").val($("#Field2").val());
  });

The "click" is just a assumption =)

Well you seem to have done the work already, all you need is something to click on to execute it:

<button onclick="doit()">click me</button>

Just use the + operator to add a string before and after the input value.

<script type="text/javascript">

function doit(){
document.getElementById('input2').value="pcid" + document.getElementById('input1').value + "d";
}

</script>
