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
nAn 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.
Note: The REPOSITION-FORWARD method corresponds to the REPOSITION statement FORWARDS option.- 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.
