#                   24.01.2019. 
#                   Disabled this test to be run on FB 4.0: added record to '%FBT_REPO%	ests\\qa4x-exclude-list.txt'.
#                   UDF usage is deprecated in FB 4+, see: ".../doc/README.incompatibilities.3to4.txt".
#                   Added EMPTY section for FB version 4.0 in this .fbt as one more way to protect from running.
