If you're storing data for calulcations why don't you store it in a CSV (Comma Separated Values) fashion,
then you can use the Split() function to extract the values into an Array, i.e.

VB Code:
  1. Dim sData As String
  2.     Dim vLine As Variant
  3.     Dim vValue As Variant
  4.     Dim lLine As Long
  5.        
  6.     sData = FileToString("C:\File.txt")
  7.  
  8.     vLine = Split(sData, vbCrLf)
  9.     For lLine = 0 To Ubound(vLine)
  10.         vValue = Split(vLine(lLine), ",")
  11.         ' Do Whatever with vValue Array
  12.     Next
