PureBasic Forums - English

I have little idea of where to begin, (apart from http://www.purebasic.fr/english/viewtop ... 342#p72342)

If using a given font name I would like to know, simply if it' Serif or Sans-Serif.
Is this easily achievable?

Any hints?

Using Sparkie's code, Is the family Roman - Serif
and Swiss - Sans-Serif
