For this specific question, there are arrays defined for exactly this 
purpose:
var formname = "bob";
var fieldname = "fred";
var ref = window.opener.document.forms[formname].elements[fieldname];
However, it is good to know that JavaScript is designed such that ANY 
property can be accessed using a string subscript like so:
var ref = window.opener.document[formname][fieldname]
or a more extreme example:
var ref = 
window["opener"]["document"]["forms"][formname]["elements"][fieldname];
