the reason it doesn't work is he is dim an array in one routine then going to another routine where the array hasn't been dimmed yet

You can Dim an array anywhere, so long as you Dim it before you use it.


I think this is the problem:



When J = the file size, you then continue to add 1, which breaks the limit of the array. It needs to be:

true, but he is going from one routine to another routine and trying to use an array that hasn't been dimensioned yet.

do you mean "<" is not working and it continues to add 1.

the test is at the beginning of the loop so this adds 1 more loop.

Yes, I think I was talking rubbish about the WHILE loop

I wouldn't have written it like this, basing arrays on one variable, and loops on another. It's a typical trap that should be avoided.
