#               
#                   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.
#               
#                   Checked on: 4.0.0.1803 SS; 3.0.6.33265 SS; 2.5.9.27149 SC.
