Re: SFLINZ (or) SFLCLR

True, but unless I've missed a recent API, you would then need to write a MI
program to use the index. I've often looked at user indices but backed off
them because of the MI. It's not that I don't like MI, but usually it's not
worth the effort.

We also added a field to the notes file for

store those blank lines.
