.DTW5 EQUB 0Name: DTW5 [View in context] Type: Variable Category: Text Summary: The size of the justified text buffer at BUF
When justified text is enabled by jump token 14, {justify}, during printing of extended text tokens, text is fed into a buffer at BUF instead of being printed straight away, so it can be padded out with spaces to justify the text. DTW5 contains the size of the buffer, so BUF + DTW5 points to the first free byte after the end of the buffer.
