Hello folks,

I'm new in this newsgroup and already want some advice from you.

Currently, I'm writing an article with LaTeX and have to make use of
the common symbols "C", "R", "Q", "Z", "N" for complex, real, rational,
integer, and natural respectively. Now I'm looking for macros (?)
(fonts?) to write them properly (and also write them easily for me).
In particular, I would like something with a left bar in "C", a 
double bar in "R", a left bar in "Q", a double slanted bar in "Z",
and a double left bar in "N" (like 'I\!\!N').

I should be surprised if people have not encountered the problem 
before me.

Thanks to all for any good hints.
