I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in its classical Greek synthetic form and in its more modern analytical/transformational form.

comment How to write the following subroutine in Mathematica and then how to call it?
This question appears to be off-topic because it is too localized; i.e, it applies only to the local situation and needs of its poster and answers will not benefit others.

Try choosing Show Fonts... from the Format menu. (The menu also shows the shortcut on OS X)

On OS X I find the font by putting the cursor into a cell and pressing Cmnd + T.

I don't think you can trust $DefaultFont‌​; it's been obsolete for a long time.

comment How to put a fixed sized frame around traditional form expression
You are more likely to get an answer if you were to edit your post to include code that could serve as a minimal working example of your problem. As it is currently posted you have not given sufficient context for me (and many others who might want to help you) to work on your problem.
