The build descriptor option checkNumericOverflow specifies whether to support numeric overflow checking in a generated COBOL program. Valid values are YES (the default) and NO.
If you specify NO, the system function sysVar.handleOverflow is ignored. Division by zero results in an abend with a message. In other overflow conditions, the result is truncated, causing the significant digits to be lost, but the generated program gives no indication that truncation has occurred.
Setting checkNumericOverflow to NO may result in smaller programs with better performance.
