Hi Sergio, [Screen] and [Printer] sections defines logical font to physical font mapping. In the default usys.ini file Uniface is providing default definitions plus those needed from UDE. You could add your own, like: myVeryLargeMono=Courier New,72,regular using whatever font available in your environment. See [Screen] and [Printer] sections into Uniface Library for more info. Regards, Gianni

Hi gianni Yes, i know i can edit my own font on usys.ini What i want is to do it dinamically for certain forms

Hi Sergio, what about using $properties (or $fieldproperties) in the INIT operation of each component to set the font you like? Greetings, Uli

It's an option. I agree.   The question if you can change the "font0" at runtime  as "the setup option" does. I checked that the usys.ini file is modified when you use this opton.

Hi Sergio, I would like it could be possible too... but while developing a special application setup to properly support a person with low vision I was forced to implement a separate, specific INI file for my startup shell. Let's hope with U10... Gianni
