The X11 Procedure

This example is similar to Example 36.1, except quarterly data are used. Tables B1, the original series, and D11, the final seasonally adjusted series, are printed by the TABLES statement. The OUTPUT statement writes the listed tables to an output data set.

data quarter;
   input date yyq6. +1 fy35rr 5.2;
   format date yyq6.;
