System Unit

Description

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 = 20 then sCompilerName := 'Delphi 2009';

or in conditional compiler expressions:

{$if CompilerVersion > 18} // Delphi 2007 or later {$ifend}

Technical Comments

The CompilerVersion constant was introduced in Delphi 6. In earlier Delphi versions various compiler defined VERxxx symbols are used to determine compiler versions.

CompilerVersion values and the equivalent compiler defined symbols for the Delphi versions in which the CompilerVersion constant is defined are:

Compiler Version Compiler Defined Symbol
Delphi XE   22 VER220 
Delphi 2010 21 VER210
Delphi 2009 20 VER200
Delphi 2007 18.5 VER185
Delphi 2006 18 VER180
Delphi 2005 17 VER170
Delphi 8 16 VER160
Delphi 7 15 VER150
Delphi 6 14 VER140
