Simple VBA Question - Search List of Strings Straight from VBA?

Basically, I'm matching 4 strings currently, and have a bunch of extra code that I am trying to clean up. These are just defined by me within the code, not pulled from any Excel Worksheet.

Is there a way to create the list in VBA and then just do a loop through the list?

So I have something similar to this:

   Dim lMatch As Long
        lMatch = Application.Match("AString", ws.Range("A1:A20"), 0)
        If Not IsError(lMatch) Then
            *some code*
        End If
        lMatch = Application.Match("BString", ws.Range("A1:A20"), 0)
        If Not IsError(lMatch) Then
            *some code*
        End If
        lMatch = Application.Match("CString", ws.Range("A1:A20"), 0)
        If Not IsError(lMatch) Then
            *some code*
        End If
        lMatch = Application.Match("DString", ws.Range("A1:A20"), 0)
        If Not IsError(lMatch) Then
            *some code*
        End If

Which you can see it's very redundant.

I wanted to just make a loop where I store my search terms in some type of array in VBA and then loop through it, but I'm not sure on the exact way to do this.

So something like:

Dim iRow as Integer
???("AString", BString", CString", DString")
For iRow = 1 to 4
    lMatch = Application.Match(???(iRow), ws.Range("A1:A20"), 0))
    If Not IsError(lMatch) Then 
         *some code*
    End If
Next iRow

Can I just return the position of the string to search from some type of array? I'm not really familiar with using this type of stuff, thanks.
