ESTBYTE - Estimated Spool Utilization for Output Exceeded

The ESTBYTE statement specifies the amount of spool space used before the $HASP375 (ESTIMATED BYTES EXCEEDED) message is initially written to the operator, the interval at which it is repeated, and the action JES2 takes if the output exceeds the estimate. Your installation can provide an output overflow installation exit routine (Exit 9) to override this statement on a per-job basis.
