[MiKTeX] pdflatex environment variables in MiKTeX

[Daniel M. <dan...@gm...>]

Hi all,
I have a question on, where certain settings are stored by MiKTeX. I am 
using version 2.7 on Win XP mostly through TeXnicCenter frontend.
The pdf(la)tex manual says in section 3.4 that there is a set of 
environment variables (among them TFMFONTS, TTFFONTS,PKFONTS...) 
containning the search path to fonts, pool files etc. They all ought to 
be defined in a file `fexmf.cnf', whose location is said to "normally" 
be texmf/web2c and which should be in another environment variable 
TEXMFCNF. I failed to locate the .cnf file or any of these variables. 
Are thery there in MiKTeX or not? If not, where does MiKTeX store the 
equivalent information?
Cheers,
Daniel
