   The changeValue event will do that, as long as you don't call doDefault   
   first.

   In the changeValue event:   
      
   var   
      stNewValue String   
      arBreak Array[] String   
      liCounter longInt   
      stBadChars String   
   endVar   
      
   stBadChars = "\n\r\t" ;// line feed, carriage return, tab   
                          ;// add additional characters as desired   
      
   stNewValue = string(eventInfo.newValue())   
      
   stNewValue.breakApart(arBreak,stBadChars)   
      
   stNewValue = arBreak[1]   
   if arBreak.size() > 1 then   
      for liCounter from 2 to arBreak.size()   
        stNewValue = stNewValue + " " + arBreak[liCounter]   
      endFor   
   endIf   
      
   eventInfo.setNewValue(stNewValue)   
      
   ...the End.
