The library of styles J is a default library that may contain additional user-defined tags and styles.

None of tags and styles, described is this chapter is required for the normal functionality of the GN4 system. In other words, what we show here is just a compact way to achieve certain typographical effects.

For example, you can type either >wedw<, or type >writei EWeekDay, ' Monday Tuesday Wednesday Thursday Friday Saturday Sunday'<. Both achieve the same effect, it's just that the first one is 4-letter tag, while the second one is 77-letter long.
