VBA Associative Arrays (How to Index) - arrays

Question

I'm a newbie to VBA so please forgive my lack of experience.
Im using excel VBA and trying to figure out how to index an array. I'm importing a CSV and using the split function. I need to access each individual items of the items split into the array(s). The best way to explain what I need is an example like this from Actionscript:
var a:Array = [];
a[1] = "Hello";
a[2] = "World";
(Except that what I have is a dynamic array created by the SPLIT function)
Where I could access "Hello" with the var a[1]
Here is what I have so far:
Sub getTxtfile()
FilePath = Application.GetOpenFilename _
(Title:="Please choose a file to open", _
FileFilter:="CSV Files *.csv* (*.csv*),")
Open FilePath For Input As #1
row_number = 0
Do Until EOF(1)
Line Input #1, LineFromFile
LineItems = Split(LineFromFile, ",")
'ActiveCell.Offset(row_number, 0).Value = LineItems(1)
'ActiveCell.Offset(row_number, 1).Value = LineItems(0)
row_number = row_number + 1
'Debug.Print LineItems(0) & ": " & LineItems(1)
Loop
Close #1
End Sub
I now have 2 arrays (LineItems(0) & LineItems(1)) but how do I index what is inside of them at this point?
Thanks for any and all help, it is greatly appreciated.

The CSV I'm using is formatted to use with other applications SolidWorks, python, etc.) besides Excel. I need to access only certain elements within the array to populate certain cells. As it is...I can pull the entire array into columns but I don't want to do that, just the ones I need. Here is a sample of the CSV:
0,.200
p,1.0709
q,1.167
r,1.177
s,1.216
t,1.570
u,1.5843
v,1.6883
w,1.9079
e,.2645
What I want to do is reference the letter in the first element and have the second element inserted in a certain cell: Reference "t" through an index and have "1.570" inserted.
The elements in my arrays are LineItems(0) and LineItems(1). So ideally I'm looking to reference each indexed item in an element as LineItems(1)(a) / LineItems(1-a) or something similar to that.

I think the commented-out lines in your code should actually work, at least as far as array access is concerned. (However, I may not fully understand what you are trying to accomplish. Would you please edit your question to clarify?) I do recommend adding
Option Explicit
Option Base 0
at the top of your file, and
Dim LineItems as Variant
before the Split call. That way the compiler will help you find errors.
However, If what you really want is to open a CSV, please allow me to suggest:
Dim wb as Workbook
Workbooks.OpenText Filename:="<filename>", DataType:=xlDelimited, Comma:=True
Set wb = Workbooks(Workbooks.Count)
which will give you a new workbook wb with the CSV parsed and ready to be accessed just like any other worksheet (docs on MSDN).

You can have associative arrays in VBA with Scripting.Dictionary object or the .NET System.Collections.HashTable, but that seems a bit overkill.
You can use Jagged Arrays (Arrays of Arrays) like this:
Line = "0,.200 p,1.0709 q,1.167 r,1.177 s,1.216 t,1.570 u,1.5843 v,1.6883 w,1.9079 e,.2645"
LineItems = Split(Line, ",")
Dim LineSubItems() ' has to be Variant or Variant() array
ReDim LineSubItems(0 To UBound(LineItems))
For i = 0 To UBound(LineItems)
LineSubItems(i) = Split(LineItems(i), " ")
Next
Debug.Print LineSubItems(1)(1) ' "p"
