Hi,

I'm new to Ultimate (which I like very much) and look for a concept idea, i.e. which elements are most suited to use.

Suppose, I have a CSV table like this:

A,B,C
1,2,3
4,5,6

Reading it line-by-line is no problem. E.g. I can store each line as a String or (already decomposed) in a Vector<String> or Vector<Value>. Once I read the table from the file I'm interested in the columns. E.g. I'd like to get column C for further manipulation:

C, 3, 6

Suppose I changed it into somethig different, like:

D,100,200

I want to assemble a new table for storage, e.g.

D,B,C
100,2,3
200,5,6

I'm not aware that there is something ready-to-use for this purpose, besides ArrayCtrl, may be.

Thank you for your help.

Kind regards, Micha
