- ; ASMCLICKLoop
- ;
- ; This routine gets called by the TextEdit Manager from TEClick.
- ; It calls the old, default click loop routine that scrolls the
- ; text, and then calls our own Pascal routine that handles
- ; tracking the scroll bars to follow along. It doesn't bother
- ; with saving registers A0 and D0, because they are trashed
- ; anyway by TextEdit.
