REPOSITION-BACKWARD( ) Method
Moves a query object’s result list pointer back a particular number of rows.
Return Type: LOGICAL Applies To: Query Object Handle
n
An INTEGER expression representing the number of rows.
REPOSITION-BACKWARD() always places the cursor between rows. For example:
- If the cursor in on a row — say, row 5 — REPOSITION-BACKWARD(1) moves the cursor to row 4, then to half way between rows 4 and 5. From this position, GET-PREV() moves the cursor to row 4, while GET-NEXT() moves the cursor to row 5.
- If the cursor is between two rows — say, between rows 5 and 6 — REPOSITION-BACKWARD(1) moves the cursor to half way between rows 4 and 5. From this position, GET-PREV() moves the cursor to row 4, while GET-NEXT() moves the cursor to row 5.
NOTE: The REPOSITION-BACKWARD method corresponds to the REPOSITION statement BACKWARDS option.
