onclick=" if(myGlobal) document.forms[0].first[0].checked=true;"

onclick=" if(myGlobal) var R = document.forms[0].first;
for(var i=0; i<R.length; i++)
if(R.value=='choice1') R.checked=true;"

or:

document.getElementById("first").checked = myGlobalVariable;

No, Rob,

Because that amounts to unchecking,
if myGlobalVariable is, or results in, false.

And that was not what the OP asked for.
