Description

Indicates whether the excecutable module was compiled as a console application.

For Windows platforms, the IsConsole variable is True if the module was linked as a console application. To specify the console application, Compiler's -$C option or {$APPYUPE CONSOLE} should be used. Otherwise, the application is in GUI mode.

If the IsConsole variable is False, the application can't use console input and output. WriteLn / ReadLn may raise the exception if the application manually opens the console.

For other platforms, the IsConsole variable is True, even if the application is in GUI mode. The application can read or write to console.
