Hi

I have a simple 3 column CSV file, I wish to assign a variable to each column in my pipeline. I have seen many other examples use something like:

    while IFS=',' read  col1 col2 col3
do
print $col1
print $col2
print $col3
done

However these variables do not persist out of the while loop, is there a way of parsing a CSV and keeping the variables for the whole of the pipeline?
