pike.git/refdoc/chapters/hilfe.xml:57:   from your hilfe expressions with the variable <expr>__</expr>. You can   either "address" your results with absolute addresses, e.g.   <expr>__[2]</expr> to get the second result ever, or with relative   addresses, e.g. <expr>__[-1]</expr> to get the last result. The last   result is also available in the variable <expr>_</expr>, thus   <expr>_==__[-1]</expr> is true. The magic <expr>_</expr> and   <expr>__</expr> variable can be shadowed with local definitions to   disable them, e.g. by typing <expr>int _;</expr>. The result history   is ten entries long by default, but it could easily be altered by   using the <tt>set history</tt> command. Note that some Pike code only - works when there is at most one object created from a class (e.g. the - Perl module), which means that the result history must be turned off. - Otherwise the previous object will remain in the history during the - next nine results.</p> + works when there is at most one object created from a class, which + means that the result history must be turned off.

All variables are kept in a mapping so that their values can   be view and altered by subsequent code lines. Every expression is
