A property of the SYSTEM built-in variable that returns the version information for the Clarion RTL DLL loaded for the EXE currently executing. Note, this could be different from the version number of the RTL in use when the EXE was compiled.

SYSTEM {PROP:LibVersion} or SYSTEM {PROP:LibVersion, 1}

Both return the **internal RTL version**, for example 801\\

SYSTEM {PROP:LibVersion, 2}

returns the **production version** of the RTL, for example 8000

SYSTEM {PROP:LibVersion, 3}

returns the **build number** of the RTL, e.g. 8839

**Example:**

** MESSAGE('Clarion RTL version ' & SYSTEM{PROP:LibVersion} & '|Build: ' & SYSTEM{PROP:LibVersion,3})**
