I am also trying to adjust the font in a digits panel without having to use a .wdl file. I would be satisfied with the internal _a4font but it is too small.
(1)Is there a way to enlarge the font without .wdl?
(2)Are there any other internal fonts (that are larger)?

jcl:"For the font the only solution at the moment is to open the engine with a small .wdl file with all necessary definitions, including a FONT definition."
(3)I have a dll that opens and runs the engine (driven by an external program), how can I attach a .wdl file to define the fonts? (please explain this)

Thanks!
