(Tested in Netscape7.2, IE6, and Firefox1/Mozilla5)

function changeAndSetScroll(box){
    scrollPos = box.scrollTop;
    //
    // make your changes to the textarea here
    //
    box.scrollTop = scrollPos;
}

<textarea name="maintext"></textarea>

<input type="button" value="Change and Set Scroll"
onClick="changeAndSetScroll(document.getElementById('maintext'));">
