| Hi,
<br />
<br />
If I have a method called Turbo.GetResponse(int dwDevice, string question, bool bAddLF, out string pAnswer, out int pstatus);
<br />
<br />
And I declare each of these variables as separate names in my Globals class, can I access them using Globals.Turbo.GetResponse(Globals.device_number, Globals.command, Globals.false, out Globals.response, out Globals.status)
<br />
