 |---------------------------------------------------------------------|
 |        setfilter()  set a filter for a cxobject from an input       |
 |                     description string.                             |
 |      setfilterix()  set a filter for a cxobject from an ix data     |

 |      freeievents()  frees the linked list of input events created   |
 |                     with InvertString().                            |
 |       addievents()  converts a list of input events to cxmessages   |
