LOOP.

ENDLOOP.
Effect
The LOOP and ENDLOOP statements define a loop around a statement block. The loop is passed for each row from the extract dataset until it is exited using one of the statements from the section Exit Loops. In each loop pass, the LOOP statement assigns the contents of the components from the current row of the extract dataset to the data objects that make up the field group of the row. If the extract dataset is not sorted, the order in which the rows are read is the same in which they were appended using the EXTRACT statement. If the extract dataset is sorted using SORT, the read order is the same as the sort order.
A LOOP loop also ends the process of structuring the extract dataset. If
you execute an EXTRACT statement after a LOOP
statement, an unhandleable exception is raised. In addition, you cannot process the extract dataset
using either LOOP or SORT within a LOOP
block. You cannot nest LOOP blocks that read the extract dataset.
