Did the block-transfer complete without errors?

yes

Sets the done .DN bit (13).

Was the block-transfer a BTR?

yes

Copies data from the active buffer to the block-transfer file in the data table.

Sets the error .ER bit (12).

yes

Is the block-transfer continuous? (the .CO bit is set.)

Frees up the active buffer for the next request
