Description

Describes the current operating system: platform and version.

Use TOSVersion to get information about the current operating system, such as:

  • Platform (Windows, MAC OS X, iOS, Android, or Linux)
  • Version

Other information:

  • Architecture (Intel x86, Intel x64, ARM 32, or ARM 64)
  • Installed service pack

Example:

Writeln(TOSVersion.ToString);

Possible output:

Windows XP Service Pack 3 (Version 5.1, Build 2600, 32-bit Edition)

You cannot create TOSVersion variables. TOSVersion represents static (global) data initialized at application start-up.

TOSVersion provides methods to check the version of the operating system. See the overloads of Check.

Note: On the Linux platform, the output is the Kernel version, not the version of the operating system.
