Hi. Vincent.
I am going to reply both of your emails from this one.

It sounds interesting to try.

Well explained Vincent. Thanks for the explanation. I do not use ses
daily. So I discover ses (three years ago). And at that time
workbook.ses was created. From that time to now workbook.ses has been my
only contact with ses (with the exception of yesterday). Just changing
values, not formulae, formulaes has been almost the same from three
years ago. But Now that You have mentioned it. Three years ago I though
why using '+ when 'ses+ always take care of blanks. So that's the one to
use when using ses. Just until now You have showed me there is a
difference. So now the question could be "why using 'ses+ when '+ is
enough even for eliminating the blank values?"

It ended like this:
--8<---------------cut here---------------start------------->8---
      (ses-setq :: sf N7 (apply '+ (ses-range N3 N6 !)))
--8<---------------cut here---------------end--------------->8---

Well. Actually I started with the simple case just using '+ and after it
I replaced with the real formulae(which contained 'ses+) as the other ones within
workbook.ses. I am happy I had try it that way. So I have learn the
difference between 'ses+ and '+. It was a happy coincidence.

BTW.
s/"Compute the sum of the arguments, ignoring blanks."/"Compute the sum of the arguments in reverse order, ignoring blanks."
Could above be ok (for improving the documentation of 'ses+)?
