Karen,

Those are the values of the different Calculation modes.

In the VBE, hit [F2], enter "xlCalculation" in the search box. In the Search
Results box, select any of the items that have "XlCalculation" in the Class
column.  Then in the "Members of 'XlCalculation'" pane below, select each
constant of the XlCalculation class, then look in the gray/tan box at the
bottom to see the values for each constant.

As far as returning the names......sorry, can't help you there.

HTH,

As Conan mentioned, xlCalculationAutomatic and xlCalculationManual are
predefined constants for the numbers -4105 and -4135. By the way, there is a
3rd possible mode... 2 whose predefined constant is
xlCalculationSemiAutomatic. While somewhat ugly, you can use this statement
to print out what I think you want...

Debug.Print "Starting NuTenant: " & _
           Choose(((Application.Calculation + 4165) Mod 4077) / 30, _
                  "xlCalculationManual", "xlCalculationAutomatic", _
                  "xlCalculationSemiAutomatic")

It handles all three modes; however, if you never use
xlCalculationSemiAutomatic, then you can use this somewhat shorter statement
instead...

Debug.Print "Starting NuTenant: " & _
           Choose((Application.Calculation + 4165) / 30, _
                  "xlCalculationManual", "xlCalculationAutomatic")
