REPOSITION-FORWARD( ) Method
Moves a query object’s result list pointer forward a particular number of rows.
Return Type: LOGICAL Applies To: Query Object Handle
n
An INTEGER expression representing the number of rows.
REPOSITION-FORWARD() always places the cursor between rows. For example:
- If the cursor in on a row — say, row 5 — REPOSITION-FORWARD(1) moves the cursor to row 6, then to half way between rows 6 and 7. From this position, GET-PREV() moves the cursor to row 6, while GET-NEXT() moves the cursor to row 7.
- If the cursor is between two rows — say, between rows 5 and 6 — REPOSITION-FORWARD(1) moves the cursor to half way between rows 6 and 7. From this position, GET-PREV() moves the cursor to row 6, while GET-NEXT() moves the cursor to row 7.
NOTE: The REPOSITION-FORWARD method corresponds to the REPOSITION statement FORWARDS option.
