What is the best practice when writing a file specification for multiple values in a column
I have to write a file specification for an import routine.
It is for a csv file.
1 of the columns can have between 0 and multiple values.
I'm wondering which is the best way to describe the file:

    colA, colB, "val1, val2, val3", col4

or

    colA, colB, "val1 | val2 | val3", col4

Or maybe another way? Or does it not really matter?!

Thanks
