[Pharo-users] Questions

Hello, my name is Alejandro. I´m writting code in Pharo 5.0. I need finish an exercise of my career. My question is: ¿Could you tell me how can read and write a CSV File? I need the code, because i don´t understand how is the use of NeoCSV or another tool for this. In the exercise, the text says: "You must Show the CashFlow por One Period with information from CashFlow.csv" ¿How can I do this? Thanks!!!
