Hi all,

It is a very basic question. But i want clear idea about how the perl
program execution was happened. I know Perl is a Interpreter language.I
need more information about whats going there internally .

could you explain or direct me right document?
snip

Perl is not interpreted. This is a common misconception. A program
written in Perl is compiled into an optree in its first stage of
running. This optree is then executed by perl. The best place to go
looking is probably "Programming Perl" (aka the Camel). Is there
something specific you want to know, or are you just curious?
