  ::: NB :::
  ### Name of original test has no any relation with actual task of this test: ###
  https://github.com/FirebirdSQL/fbtcs/blob/master/GTCS/tests/CF_ISQL_27.script

  Discuss in fb-devel (subj: "Vulcan, CF_ISQL_27.sql"):
  https://sourceforge.net/p/firebird/mailman/message/17631672/

  Author said that example from this test did not return any error (and he expacted this)
  plus either did not return value into output parameter or even lead server to crash
  (when such SP was called twise).
  For current FB versions no error occurs and output value is issued w/o any problems.
