    Hi,

    Query the Command$ variable in your VB code.

    In the above example, it will contain "JU1991020005 940604707218.txt  940604707218.idx".

    BFN,

    I think you can get by using the command function.

    sub frmmain_load()
       frmmain.text1 = command
    end sub

    Assuming your still using the above, untested.

    Sub Form_load()
      Dim CommandArgs
      Dim cmdFilename as string

     
      CommandArgs = Split(Command(), " ")
      CommandArgs(0) will contain your first argument
      CommandArgs(1) will contain your second argument
       cmdfilename =  left(CommandArgs(1), len(CommandArgs(1))-3)

       Open app.path & "\" & cmdfilename & "doc" For output As #1
             Print #1, "File created."
       Close #1
       

    End Sub
