I have a sub routine in my rules to write to file.

It contains a line that says: Const ForReading = 1, ForWriting = 2, ForAppending = 8

What do each one of these do?

Write?
Read?
Append?

I usually use append but it seemed to be placing duplicate items in the file each time I ran it.

Then I tried the write and it only gave me one record.

Thanks!




Here is the entire sub routine:

Sub WriteToFile(txtStringToWrite,FName)
On Error Resume Next
Const ForReading = 1, ForWriting = 2, ForAppending = 8
Dim fso, f
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile("C:\Hyperion\Extracts\" & FName, ForAppending, True)
f.WriteLine txtStringToWrite
f.Close
On Error GoTo 0
End Sub 'WriteToFile
