<script> 
 var disp_txt = "Hello this is Samar's Pain Text Scroller"
 var width=50 
 function scroll()
  {
   var space = " "
   msg = disp_txt 
   for(x=0; x<width; x++ )
     { space += " " }
   if (width< 0)
     {
      space = disp_txt.substring( -width, disp_txt.length )
     }
   else space = space + disp_txt
   document.sform.field.value = space
   space = " "
   setTimeout( 'scroll()', 30 )
   width--
   if (width< -disp_txt.length )
     {
      width = 50 
     }
  }
</script>
<center>
<form name="sform">
<!-- <input type="button" value="start" onClick="scroll()">
-->
<input type="text" name="field" size="50">
</form>
</center>

Note -
- var width must be global variable
- If the if condition is changed to if width < -disp_txt.length then the text sticks at the end as it displays it at the last position for some time
- The last if loop (if width < 0) then text does not scroll full to left if width<0, then use substring to display only part of string button can also be used to start program instead
