SUMMING

The CHECK statement is used to define whether BCHECK is to perform a sort check or a summing check and an overall check or an incremental check.

You must enter the CHECK statement among the control statements.

If a preceding check detected local consistency errors, these should be corrected before a sort check, otherwise a very large number of global consistency errors may be reported which are only due to the local inconsistencies.
