Assertions are a way of breaking out of code when there is an error or an unexpected input.

Some languages throw exceptions and some treat it as a break point.



Task

Show an assertion in your language by asserting that an integer variable is equal to 42.




sub Assert( boolExpr, strOnFail )
	if not boolExpr then
		Err.Raise vbObjectError + 99999, , strOnFail
	end if
end sub
