CHKP is a service call to save some of the data in the log DataSet, when the program failed, then restart the program to get the data back and do whatever you want to do right?

For example:
I have 100 records need to write into database and I send a CHKP call with count number in every 10 records.

10 -> CHKP count = 10
20 -> CHKP count = 20
24 abend

After I restart my program, the XRST will get the number 20, then I just bypass them start from 21.
