Scalable font for large text display in programs?

[deSitter]

Sorry my earlier post seems to have gone into the ether.

I need to display large numeric data with normal sized text. This has to be visible in the dark (telescope work) and red on black color. The built-in font for the input screen is way too small even at the "large" setting. In general, what are the font options? Is there a TTF display library around? Any of the programming environments will do. I have a rev. D Prime.

Thanks in advance.
