Hi, is there any way to adress the row index number within colums to do such an easy thing like: col(b) values= (col(a)i) - (col(a)i-1)...

so in this case to substract the former value i-1 of a column from the actual value i of the same or any other column?

many thanks in advance!

Hi Eric,

You may make use of the Set Column Values tool (a context menu when right click on a whole column).

Fill formula 
col(a)[i+1]-col(a)[i]


Or you can use a built-in function to do the calculation:
diff(col(a))


Hope it helps.
