CREATE

CREATE produces new series as a function of existing series. You can also use CREATE to replace the values of existing series.

CREATE new series={CSUM (series)                       }
                  {DIFF (series, order)                }
                  {FFT (series)                        }
                  {IFFT (series)                       }
                  {LAG (series, order [,order ])       }
                  {LEAD (series, order [,order ])      }
                  {MA (series, span [,minimum span])   }
                  {PMA (series, span)                  }
                  {RMED (series, span [,minimum span]) }
                  {SDIFF (series, order [,periodicity])}
                  {T4253H (series)                     }
 
[/new series=function (series {,span  {,minimum span}})]
                              {,order {,order       }}
                                      {,periodicity } 

This command reads the active dataset and causes execution of any pending commands. See the topic Command Order for more information.
