Description[edit | edit source]
The RTLVersion constant in de system unit provides you with information about the compiler series that the RTL belongs to and the patch number.
This information is important in scenario's where sourcecode needs to be maintained or recompiled or to check if the latest RTL patches for a certain compiler series are applied.
It takes the format xx.y where xx is the main compiler version and y is the revision number.
See the CompilerVersion Constant for further information on how to use it.
