Such a thing as End Of Variable when reading from var? Like EOF when reading from file?

I'd like to be able to read from a variable, line by line, w/o having to first count the number of lines in the variable.  Loop until EOF works great when reading from a file via line input and it'd be great if I could use something similar to that when reading from a variable (line by line).

I'm asking because I need to "flip" the contents of a .txt file and make the bottom (last entry) the top (first) and vice-versa. The only way I know how to do this is to read the file, line by line and dump it into a new file (or back into its own). Thanks.

You can split it into an array using something like this:

Dim MyVar as string
Dim arrLines() as string

MyVar = "your variable data ........"

arrLines = Split(MyVar,vbCrLf)

' loop through array
Dim x as Long
For x = 0 to Ubound(arrLines)
   MsgBox arrLines(x)
Next x

You could rebuild the variable backwards then write it back to the file:

Dim x As Long
MyVar = ""
For x = UBound(arrLines) To LBound(arrLines) Step -1
   If MyVar = "" Then
     MyVar = arrLines(x)
     MyVar = MyVar & vbCrLf & arrLines(x)
   End If
Next x

Open "Myfile.txt" for output as #1
Print #1, MyVar
Close #1
Maybe put it into a function:

Private Sub Command1_Click()
FlipFile "C:\MyFile.txt"
End Sub

Private Sub FlipFile(sFileName As String)
Dim ff As Integer, fData As String
Dim arrLn() As String, x As Long
ff = FreeFile
Open sFileName For Input As #ff
fData = Input$(LOF(ff), ff)
Close #ff

arrLines = Split(fData, vbCrLf)

ff = FreeFile
Open sFileName For Output As #ff
For x = UBound(arrLines) To LBound(arrLines) Step -1
    If Trim$(arrLines(x)) <> "" Then
        Print #ff, arrLines(x)
    End If
Next x
Close #ff
End Sub
uhh, I meant a sub not a function.
