Inserting command line Arguments into vbscript

Hey I have this code were I take two documents and read them. The two are CurrentShares and ApprovedShares. I compare these two and write the differences into a .txt file then I run a command to delete the shares, the command is Net Share ShareName /DELETE. That was the whiteList section.

The blacklist section is fairly the same, I take the previous CurrentShares and compare it to the UnApprovedShares. I then write the differences to a text file and delete the shares using the same command as before.

What I need is to seperate my script so when someone runs the script from the command line all they have to do is write ShareDelete.vbs /Whitlist or ShareDelete.vbs /Blacklist and depending on which one they type the command calls either the blacklist or whitelist verson. my code is

Option Explicit

Function DeleteThisShare(Share)
Dim objShell
   DeleteThisShare = "net share " & Share & " /DELETE"
    Set objShell = CreateObject("Wscript.Shell")
    wscript.echo DeleteThisShare
    objShell.Run DeleteThisShare
End Function
