How to read a specific line from txt file?

I wan't to read lats say, line 5 how can I do it?


BTW:
How can I know the end (number) of array?
Or how can I check if array1(3) is ok? (If it's exist)

for the Array uBound(array1)

Great,
Now I don't even need my first question :)
I can use "split" & "Ubound"

You help me a lot!
