I started to reply, but realized I don't know enough of what you wanted to do.
What do you want the end result to be? A List so that it can saved with File.WriteList?
What do you want each line in the output to look like?
How is LineArray dimensioned, and what type of object (Int, String..)
'You don't need CRLF
Dim LineArray(30,4) As Int 'or Float or String or ...
Dim data As List
For i = 0 To 29
data.Add(Array(LineArray(i,0), LineArray(i,1), LineArray(i,2), LineArray(i,3)))
