Hello all,   Our company uses several Delphi versions and I want my code to compile without warnings on all these versions.   When I compile one of my units with Delphi Rio, the compiler emits a warning that "sysutils.searchbuf" is deprecated and has moved to the "ansistrings" unit.   No problem, but how do I find out in which Delphi version this transition was made?  I'd like to write an appropriate {$IF compilerversion} around my code block to suppress the warning and keep it functional across all Delphi versions.       Kind regards, Arthur
