如何查當前Delphi版本宏VERXXX和編譯版本號CompilerVersion

現在Delphi的版本更新速度太快基本上一年一個版本，但有些花錢買的老控件想安裝到最新的Delphi上因爲裏面的版本宏沒定義導致安裝失敗，解決方法就是自己去宏定義裏面加一個當前版本的Delphi版本宏就可以正常安裝。

 如果自己查看當前最新的Delphi的編譯版本號和版本宏呢？

我前版本是Delphi 10.3

編譯版本號CompilerVersion：

這個在Delphi裏其實定義的是一個常量用一句代碼就能得得到

ShowMessage(FloatToStr(CompilerVersion));//33

版本宏VERXXX：

到安裝目錄中找到這個文件裏面有定義

D:\Program Files (x86)\Embarcadero\Studio\20.0\source\Indy10\System\IdCompilerDefines.inc
