Syntax
REPOSITION-BACKWARD ( n )
|
-
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.
