Subject: Re: Novice: Each and p

Hello Thorsten,

	judging from the email address you might 
be abloe to read German:
http://approximity.com/rubybuch/

About "each" look at
http://www.approximity.com/rubybuch2/node24_main.html
and especially read "Iteratoren".


If not, look at the excellent 
online book by the pragmatic programmers:
http://www.rubycentral.com/book/index.html

A quick way to get info on let's say 'p'
is to use ri.
>ri p

armin@linus:~/articles/refactoring> ri p
-------------------------------------------------------------- Kernel::p
     p( [anObject]+> ) -> nil
------------------------------------------------------------------------
     For each object, directly writes anObject.inspect followed by the
     current output record separator to the program's standard output. p
     bypasses the Ruby I/O libraries.
        p self
     produces:
        main

You can get ri from
http://www.rubycentral.com/downloads/ri.html

I hope this helps,

Armin.
