 Not using eval EVER i cant remember if you need to add () or not...

Thanks Alex, together with TJ's reply I have plenty to chew on for now.

Not sure what u mean Bill...

Are you reffering to somehting like the onComplete of Ajax.Updater...

If so there is 2 ways to do it..

1. onComplete: myFunction (then somewhere else)

function myFunction() {
alert('i got called');
}

OR
2. (Anonymous Function)
onComplete : function() {
alert('I Got called');
}

  I suspect this is not a prototype question, but then again, every time I turn 
around I am learning new capabilities of the framework.

  I need to pass a function name as an argument to a function for a call-back 
function.
  Do I just pass the function name as a quoted text argument ?
  If I do, do I need to eval the function when I want to execute it.

  or...

  what is the best way of doing this ?

  My apologies in advance if prototype does not have a nifty way of doing this 
and my thanks in advance for any suggestions.
