I have got together this quick script

myDocument = app.activeDocument
with (myDocument){
	myPage = pages.item(0);
	with (myPage){
		myTextFrame = textFrames.item(0);
		with (myTextFrame){
			myStory = myTextFrame.paragraphs.item();
			app.findPreferences = null;
			app.changePreferences = null;
			myStory.search("roy", false, false, "ROY");
			}
		}
	}

The script only seraches the first paragraph. I have tried various things to make it act on the whole story with no success. Also, what are the flase comments relating to in the search command? I have looked through the scripting guide, and found not much to help me.

Thankyou in anticipation!
