The getline is a tricky function to use and it can hold surprises. For example, if you use getline in the form getline f then this also changes the variable NR and FNR, so if you first do 4 getlines to get the header into variables or arrays, then when reading the first line after the headers, NR and FNR are equal to 5. This may, or may not be what you expect..
