Example - FreeFile Function
To use this example, create a folder named e1 on your c:\ drive. When you run the script, it then creates three files TEST1, TEST2, TEST3 in that folder. It then reads the contents of the first TEST1 file.
Sub Main()
Dim Mx, FileNumber
For Mx = 1 To 3
FileNumber = FreeFile
Open "c:\e1\TEST" & Mx For Output As #FileNumber
Write #FileNumber, "This is a sample."
Close #FileNumber
Next Mx
Open "c:\e1\test1" For Input As #1
Do While Not EOF(1)
MyStr = Input(10, #1)
MsgBox MyStr
Loop
Close #1
End Sub
