Export to a fixed-width textfile

This macro exports the values or formulas from a worksheet range to a fixed-width textfile:

Sub ExportRangeAsFixedText(SourceWB As String, _
    SourceWS As String, SourceAddress As String, _
    TargetFile As String, LeftAlign As Boolean, _
    SaveValues As Boolean, ExportLocalFormulas As Boolean, _
    AppendToFile As Boolean)
' Exports the data in Workbooks(SourceWB).Worksheets(SourceWS).Range(SourceAddress) to
' the textfile TargetFile in fixed-width format, 
' uses the column widths in SourceAddress as field lengths
' Example:     ExportRangeAsFixedText ThisWorkbook.Name, _
    "ExportSheet", "A3:E23", _
    "C:\FolderName\FixedWidthText.txt", False, True, True, False

Dim SourceRange As Range, A As Integer, aCount As Integer
Dim ColWidth As Integer, eCount As Long
Dim r As Long, c As Integer, totr As Long, pror As Long
Dim fn As Integer, LineString As String, tLine As String
    ' validate the input data if necessary
    If Application.WorksheetFunction.CountA(Range(SourceAddress)) = 0 Then Exit Sub
