Hello,
Here is the code that searches through the file I describe in my other post, also include are some other functions I made to make searching through files easier. Keep in mind that some of the code may be bloted due the time I had to finish it. I hope other people find this code helpfull. Let me know if anyone has any suggestion for the memory hording problem(this code is not where the problem occurs).
