I would like to be able to evaluate the value of the named constant
sSPEC_NAME in the active workbook by using application.evaluate, as
follows:

Dim vTest as Variant

vTest = Application.Evaluate("'" & Application.ActiveWorkbook.Name &
"'!" & sSPEC_NAME)

This works fine, except where ActiveWorkbook.Name contains a single
quote, which causes the string being evaluated to become nonsense. Can
anyone suggest an alternative approach?

The most obvious to me would be

vTest =
Application.Evaluate(Application.ActiveWorkbook.Na mes(sSPEC_NAME).RefersTo)

but the issue then is that this will raise a runtime error where there
is no constant named sSPEC_NAME in the active workbook. Ideally I
would be to escape the single quote somehow in the first approach - is
there a way to do this?

TIA
