Thank you for your response. The 2 file structure is merely to mimic what I am trying to do for a more complicated program. I have to refer to another file which has for a particular "fruit", a + or -. From the information held in that file I then act on the data in the other file.

My files are 44,000 lines long and created from some hefty scripting way out of my control, so needs to be kept in this structure.

Will give this a go, thank you.
