UNDEFINED

 ERROR:  The object pointed  to  in  the  message  was  either  never
 defined  or  not  defined  prior  to  this point in the module.  The
 compiler requires the object to be defined before you refer  to  the
 object.

 USER ACTION:  Check for  a  misspelling  of  the  object's  name,  a
 missing  declaration  for  the object, or declaring the object after
 its first reference.  If names in the module are case-sensitive, the
 spellings  of  the name in the declaration and in the reference must
 match exactly.
