Hi Iggboert,
Let's assume that both two columns col(A) and col(B) in your worksheet have missing values, then you are try script as below
wxt "col(A)[i]==0/0||col(B)[i]==0/0" sel:=1; //Select the missing row.
menu -e 36442; //Delete the select data range. It is equal to the Delete item in menu.
where wxt is an x-fucntion, which can be used in Labtalk script, and is used to extract the data, also can be used to select the data from worksheet. For more details, you can refer to this page.
