ANS LabellingThe Forth Foundation Library is written in ANS-standard forth. But it requires some extensions. All those extensions are listed in one config source file which is forth engine specific. One exception is the word: include filename. This word is used to include all modules. This is not a big problem, because this word is quite common in forth engines.
