UnitEdit

DescriptionEdit

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 CommentsEdit

The CompilerVersion constant was introduced in Delphi 6 along with conditional expressions. 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:
