Any ideas anyone?

I found this example of intel hex format:

:10008000AF5F67F0602703E0322CFA92007780C361

The first character (:) indicates the start of a record.
The next two characters indicate the record length (10h in this case).
The next four characters give the load address (0080h in this case).
The next two characters indicate the record type.
Then we have the actual data.
The last two characters are a checksum (sum of all bytes + checksum = 00).


Does the record length mean the length in bytes to represent the data section?
How is the load address determined?
How is the checksum determined?
