Hi Si,

You can change the font of _Screen object before the printing of the text for e.g.

_Screen.Fontsize = 18
@2,2 SAY "Heading1"
_Screen.Fontsize = 14
@4,2 SAY "SubHeading"
_Screen.Fontsize = 10


You should try @.. TO .. command instead of @BOX command.

P.S : Better option is you create the Shape Object at run time..
