  This command removes one or more variables. Each name is a variable name,
  specified in any of the ways acceptable to the _ss_ee_tt 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 uunnsseett 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.
