The latest Delphi version number control

The CompilerVersion constant identifies the internal version number of the Delphi compiler. It is defined in the System unit and may be referenced either in code just as any other constant:

If compilerversion = scompilername: = ' Delphi 2009 ';

or in conditional compiler expressions:

{$if compilerversion >}//Delphi or later {$ifend}

Technical Comments

The CompilerVersion constant is introduced in Delphi 6 along with conditional expressions. In earlier Delphi versions various compiler defined VERXXX symbols is used to determine compiler versions.

CompilerVersion values and the equivalent compiler defined symbols for the Delphi versions in which the CompilerVersion Co Nstant is defined is:
