**Model**- Required. Is a unique identifier that designates an X-12-ARIMA model created earlier with the X12 Wizard.
**Step**- Optional. Is the offset of the target data point beyond the end of the input time series sample. If missing, NumXL assumes step = 1.
**Return**- Optional. Is a number that determines the return value type: 1 (or missing) = Forecast Value, 2 = C.I. Lower Limit, 3 = C.I. Upper Limit.
Value Return 1 or omitted Forecast mean value ( **default**).2 The lower limit of the confidence interval. 3 The upper limit of the confidence interval.

* *Warning

X12AFORE(.) function is deprecated as of version 1.67; use the X13ASFORE(.) function instead.
