use vectors in spreadsheet

[dalupus]

ok that works.

1 more question on these spread sheets.
If I enter in something in say C1 and then later decide I want to just define something for the entire column C instead, I can't get it to use what I define for the column in C1 as well since I had something in there. I've tried everything I can think of to clear it out but can't get it to clear.

Also the switching in and out of cas seems to be a little flakey. Now it is working without cas but giving a list of the concatenation of everything in columns 1 and 2 in every column 3 when I turn on cas.
