Thanks to Skip's advice I went to the VB Script forum and received some additional support from them. However, it appears that the Attachmate VB Editor contains an older version of VB, or at the very least a subset of what's available in the Excel VB Editor. I needed to use the Excel VB Editor to compile and run the following macro - in the Attachmate VB Editor it won't compile.

'
' Establish Sleep subroutine from kernel32.dll file.
'
Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sub Aut

pen()
'
' Set up system variables.
'
Dim myShell As Object
Dim myExplorerWindow As Object
Dim iCnt As Integer
Dim WshShell As Object
'
' Establish location of comment files.
'
Dim FolderPath As String
FolderPath = "G:\Desktop Folder"
'
' Load Windows Explorer.
'
Set WshShell = CreateObject("WScript.Shell")
WshShell.Run "explorer"
Sleep 3000 ' Pause for 3 seconds.
' WshShell.AppActivate "Explorer"
'
' Set explorer to folder path.

WshShell.SendKeys ("{Enter}")

Thanks so much to everyone who assisted in this process! Very much appreciated.
