The FIFO DAT maintains a user-set maximum number of rows in a table. You add rows using the
appendRow() method found in DAT Class. When its capacity is reached, the first row is removed. After the maximum number of rows is reached, the oldest row is discarded when a new row is added.

callbacks- The script is executed from the location of the DAT specified in the Callbacks DAT parameter.
- Specified Operator
op- The script is executed from the operator specified in the From Operator parameter below.
