Hi,
At PBO you can set the cursor on a specific field of a specific row of a table control.
SET CURSOR FIELD f LINE lin [OFFSET off].
Using the optional addition OFFSET, you can enter the offset of the cursor in the field as described under setting the cursor position.
At PAI you can read the current cursor position.
