Refer to original sheet

I have an excel sheet where I run my vba program from. That program adds several new sheets. I need to refer back to the original sheet. Is there a way to do this? I don't want to use the name of the sheet because this program will be run from several different sheets.
Thanks

Declare an Excel.Worksheet and Set it to your original worksheet.

Dim xlSH as Excel.WorkSheet
'Before adding any other sheets
Set xlSH = Application.ActiveSheet
'Now you can refer to your original sheet my using
xlSh.Whatever

Thank you very much.
