The GET TRANSACTION DATA statement is used to read the data
saved with a previous END
TRANSACTION statement.
GET TRANSACTION DATA does not create a processing loop.
Note:
For DL/I: The GET TRANSACTION DATA statement
retrieves checkpoint data saved by an END TRANSACTION
statement.
The content of the Natural system variable
*ETID
identifies the transaction data to be retrieved from the database.
If the GET TRANSACTION DATA statement is issued and no
transaction data are found, all fields specified in the GET TRANSACTION
DATA statement will be filled with blanks regardless of format
definition.
 |
Warning: Make sure that arithmetic operations are not performed on "empty" transaction data, because this would result in an abnormal termination of the program. |
The GET TRANSACTION DATA statement is only valid for
transactions applied to Adabas databases, or to DL/I databases
in a batch-oriented BMP region (in IMS TM environments only).
