I started work on the clean up of E0000 and E0001 tonight.  These are reverse communication zero finders.  Most of the routines in DCDFLIB so far can be cleaned up with visual inspection.  I found myself drawing flow charts and making notes for the code flow in E0000.  The logic is fairly clear, but the code grouping and the number of goto's make the code difficult to follow.  I also see some opportunities to improve the performance of the two routines, or rather, to improve the performance of the calling routines.

Hopefully, I can get these done by tomorrow night.
