OUTFCST OUTFORECAST
determines whether forecasts are included in certain tables sent to the output data set. If OUTFORECAST is specified, then forecast values are included in the output data set for Tables A6, A7, A8, A9, A10, B1, D10, D10B, D10D, D16, D16B, D18, and E18. The default is not to include forecasts. The OUTFORECAST option can be specified in either the X11 statement or the FORECAST statement with identical results.
You don't have to send output to HTML, you can send output to a text file and then the ODS TRACE and ODS OUTPUT should work fine.
