Dialog programming - how to set text of a box at runtime?

Hi,

I'm in a middle of visual (dialog) programming in ABAP and have few related questions.

1. I have (few) boxes on my screen and I wish to set its text (that's the one which appear in the left upper corner of the box) dynamicaly at runtime depending on what details are shown within the box.

Is it possible, and if yes - could someone share his/her knowledge here?

2. Is it possible to dynamicaly change the position of the visual element (for example, box) on the screen? I successfuly manipulate the visibility of the box, but can't manage the position of the boxes rest ot the screen. Is it possible and how?

Many thanks in advance.

Regards,
