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.

Technical Comments

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:

Compiler	CompilerVersion	Defined Symbol
Delphi 10.4 Sydney	34	VER340
Delphi 10.3 Rio	33	VER330
Delphi 10.2 Tokyo	32	VER320
Delphi 10.1 Berlin	31	VER310
Delphi 10 Seattle	30	VER300
Delphi XE8	29	VER290
Delphi XE7	28	VER280
Delphi XE6	27	VER270
AppMethod 1	26.5	VER265
Delphi XE5	26	VER260
Delphi XE4	25	VER250
Delphi XE3	24	VER240
Delphi XE2	23	VER230
Delphi XE	22	VER220
Delphi 2010	21	VER210
Delphi 2009	20	VER200
Delphi 2007 .NET	19	VER190
Delphi 2007	18.5	VER185 (also VER180)
Delphi 2006	18	VER180
Delphi 2005	17	VER170
Delphi 8 .NET	16	VER160
Delphi 7	15	VER150
Delphi 6	14	VER140
Delphi 5	13(*)	VER130
Delphi 4	12(*)	VER120
Delphi 3	10(*)	VER100
Delphi 2	9(*)	VER90
Delphi 1	8(*)	VER80

(*) These versions did not have a CompilerVersion constant, it was introduced with Delphi 6.

Examples

if CompilerVersion = 20 then
  sCompilerName := 'Delphi 2009';

or in conditional compiler expressions:

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