Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Private xui As XUI
    Type Information(LabelName As String,spl As String,icon () As Byte,id As String,name As String,version As String,Model As String )
    Type cmd(spl As String,code As String )
End Sub
