iSeries EXTRA: Ending those Decimal Data Error BluesJuly 2003 | by Jon Parisand Susan Gantner

Of course, the code to report and f ix the errors (F) can be challenging in an example like this, because three fields may be in error. If you only plan to report the

records in error and skip them, this code does the job. But suppose you want to be more specific in detecting which field is in error and perhaps move a default value

to the field containing invalid data. Let's examine some options for detecting the specific field in error.

An obvious approach would be to use three separate MONITOR blocks - one for each field. This requires some duplicate code and might be cumbersome. An

alternative is to use a single MONITOR block and set a flag before processing each field. In the event of an error being signaled, the flag can be checked to

determine the field in error. To allow for the possibility that you're unfortunate enough to have more than one invalid field value in a single record, you must do the

checking iterat ively. An example of using the MONITOR iteratively can be found at on our Web site.

We're still f inding new ways to make use of some of these recent enhancements. We'll illustrate other examples in future issues of iSeries EXTRA.
