hi, i am trying to traverse subdirectories in my final project and it wont get the second, or for that matter, the third subdir's listing, please help, here's my listing code
code:

import GUI
var driveChooseWin : int := Window.Open ("graphics:850;300,nobuttonbar,position:center;truemiddle,title:Choose the Drive")
var stream : int
var files:array 1..5000 of string
var continue : int := 0
Window.SetActive (driveChooseWin)
GUI.SetBackgroundColour (black)
locate (1, 1)
Text.Colour (white)
Text.ColourBack (black)
put "Choose the drive and Folders.  Select one only"
put "(one chance to select), "
put "or else an unresolved error will"
put "occur."
Text.Colour (black)
Text.ColourBack (white)
proc setContinue
    continue := 1
end setContinue
var fileToOpen : string
var drive : string
var listing : int
var dirToOpen : string := ""
proc driveChooser (x : int)
    if x = 1 then
        if stream not= 0 then
            Dir.Close (stream)
            drive := "A:/"
            stream := Dir.Open (drive)
            put stream
        else
            drive := "A:/"
            stream := Dir.Open (drive)
            put stream
        end if
    elsif x = 2 then
        if stream not= 0 then
            Dir.Close (stream)
            drive := "C:/"
            stream := Dir.Open (drive)
        else
            drive := "C:/"
            stream := Dir.Open (drive)
        end if
    elsif x = 3 then
        if stream not= 0 then
            Dir.Close (stream)
            drive := "E:/"
            stream := Dir.Open (drive)
        else
            drive := "E:/"
            stream := Dir.Open (drive)
        end if
    elsif x = 4 then
        if stream not= 0 then
            Dir.Close (stream)
            drive := "H:/"
            stream := Dir.Open (drive)
        else
            drive := "H:/"
