See Re: Hacking .frx file Message #867112 and Re: Group to start from a new page or NOT ? Message #828946

>2- a parameter for stretching a field: the user can decide weather or not stretch a field.

You can put 2 fields on top of each other, one stretchable and another not, and control wich one to print with Print When.
