/SUBSYSTEM

Syntax:

/SUBSYSTEM:{CONSOLE|WINDOWS|NATIVE|POSIX|WINDOWSCE}[,major [.minor]]

Tells the operating system how to run the executable file. The subsystem is specified as follows:

• The CONSOLE subsystem is used for Win32 character-mode applications. Console applications are given a console by the operating system. If main or wmain is defined, CONSOLE is the default.
• The WINDOWS subsystem is appropriate for an application that does not require a console. It creates its own windows for interaction with the user. If WinMain or wWinMain is defined, WINDOWS is the default.
• The NATIVE subsystem is used for device drivers.
• The POSIX subsystem creates an application that runs with the POSIX subsystem in Windows NT 4 or Windows 2000.
• The WINDOWSCE subsystem is not used by Visual Fortran.

The optional major and minor version numbers specify the minimum required version of the subsystem. The arguments are decimal numbers in the range 0 - 65535. The default is version 3.10 for CONSOLE and WINDOWS and 1.0 for NATIVE.

The choice of subsystem affects the default starting address for the program. For more information, see the /ENTRY option.
