Hi Sean,
Please add the OUTFORECAST option to the FORECAST statement, and table B1 to the OUTPUT statement in your PROC X12 code. This should extend table B1 for each variable in your VAR statement with the LEAD= forecasts and write them to the OUT= data set specified in your OUTPUT statement. These forecasts will be on the original scale of your data. Note that if you want the confidence limits in addition to the forecasts, then you will need to use the ODS OUTPUT statement as in your current application.
If the above modifications to your code do not allow you to obtain the forecasts in the OUT= data set, then please indicate the release of SAS you are running.
I hope this helps!
