1) Starting Record No.
The Starting Record No. is accumulated by the number of records in one window after
reading the records in that window. If the new Starting Record No. is larger than the
Latest Serial No., then the Starting Record No. equals to the Latest Serial No. of Records
plus 1.
For example, the initial Starting Record No. of Records is 34, after reading 8 records in one
window, the Starting Record No. automatically turns into 42.
2) Records number

maximum record number in one window
The MAX number of records is 240 divided by the size of bytes of one record.
