Depending on the output options specified, multiple observations are written to the OUT= data set for each time period. The different parts of the results are contained in the VAR statement variables in observations identified by the character variable _TYPE_ and by the ID variable.

For example, the following statements use the OUTLIMIT option to write forecasts and 95% confidence limits for the variable SALES to the output data set PRED. This data set is printed with the PRINT procedure.

proc forecast data=past interval=month lead=10
              out=pred outlimit;
   var sales;
   id date;
run;

proc print data=pred;
run;

The output data set PRED is shown in Figure 15.3.
