Spreadsheet

[Björnke von Gierke]

Hi David

Unfortunately, I don't have any spreadsheet to share. I would be 
interested in your OpenOffice code though, any chance of making an 
example stack which contains your snippets?

As for formula handling, is there a special format you had in mind with 
"standard formulae"? Otherwise you could do (hehe) something like this:

1. Make up your code, as similar to rev code as possible. For example 
(off the top of my mind):
cell 1,3 + cell 1,4 / cell 1,5

2. Replace stuff rev doesn't understand with rev stuff (assuming every 
cell is a rev field):
field "cell 1,3" + field "cell 1,4" / field "cell 1,5"

3. evaluate the string in rev:
put value(field "cell 1,3" + field "cell 1,4" / field "cell 1,5") into 
field "cell 1,6"

You could of course use "do" as an alternative, I'm not sure if that'd 
be more complex, but it would certainly be less secure.

have fun
