| series | Field or subfield | | Data for which to return the sum of squares |
| Function result | Number |  | Sum of squares of series |
Description
Sum squares returns the sum of the squares of series. If series is an indexed field, the index is used to find the sum of the squares. You can only use a field with this function when printing a report.
Example
The following example is an object method for the variable vSquares. The object method assigns the sum of squares for a data series to vSquares. The vSquares variable is printed in the last break of the report:
vSquares:=Sum squares ([Table1]DataSeries)
The following method is called to print the records in the selection and to activate break processing:
ALL RECORDS ([Table1]) ORDER BY ([Table1];[Table1]DataSeries;>) BREAK LEVEL (1) ACCUMULATE ([Table1]DataSeries) OUTPUT FORM ([Table1];"PrintForm") PRINT SELECTION ([Table1])
Note: The parameter to the BREAK LEVEL command should be equal to the number of breaks in your report. For more information about break processing, refer to the printing commands.
