     NAME
          unset - Delete variables

     SYNOPSIS
          unset name ?name name ...?
     _________________________________________________________________


     DESCRIPTION
          This command removes one or more variables.  Each name is  a
          variable  name,  specified  in any of the ways acceptable to
          the set command.  If a name refers to an element of an array
          then  that  element is removed without affecting the rest of
          the array.  If a name consists of  an  array  name  with  no
          parenthesized  index, then the entire array is deleted.  The
          unset command returns an empty string as result.   An  error
          occurs  if  any  of  the  variables  doesn't  exist, and any
          variables after the non-existent one are not deleted.
