How to compile in earlier versions using new keywords?

Maybe I do not understand. If a new native word is present in a certain version, it will not be recognized in an earlier one. There is no way to compile, it, any more than if you used any other extraneous word.

Perhaps there is a way to have a text field that holds the appropriate script for the version, then you can set the script of btn xyz to fld "best script" on startup.
