Supported ANS Forth word sets

The words in the following sections are supported by 4tH; external words are in italics, preprocessor words are underlined. Please note that due to 4tHs special architecture some words may behave slightly different, so some "ANS Forth Programs" using these words may need modifications in order to run properly. More words are available in source and can be loaded when required.
