Rules

The cursor is repositioned before the first result row (if any) of the statement specified and SQLSTATE, SQLCODE and other SQLCA values are set.

With POSITION TO NEXT, the cursor is positioned to the next statement.

With POSITION TO STATEMENT, the cursor is positioned to the specified statement.

The cursor can be positioned either forward or backward from the current statement and can be repositioned to a given statement as many times as the application requires.

For COBOL programs with multiple compile units, the cursor can only be positioned backward if a REWIND or POSITION TO STATEMENT occurs in the same compile unit as the declaration and the opening of the cursor.

POSITION is valid with any cursor except an insertion cursor.

The statement set found by the cursor is not re-executed, but the cursor position in the spool file is adjusted accordingly.

You cannot execute POSITION as a dynamic SQL statement.
