Assign worksheet to Global variable. Possible? or Worth it?

[POE333]

So, I have found this works.. Oddly enough, part of the answer was derived from a completely different question.

What I would like to know is how I can use these as global variables across all modules.

Option Explicit

Sub SelectPages()
    Dim WB1 As Workbook
    Dim SH1 As Worksheet
    Dim SH2 As Worksheet
    Set WB1 = ThisWorkbook
    Set SH1 = WB1.Worksheets("Sheet1")
    Set SH2 = WB1.Worksheets("Sheet2")
    SH1.Select
    SH2.Select
End Sub
