It is meant to be entered exactly as written on the command-line. It is the same way we call Perl programs: >perldoc -f my is a call to the perldoc program or [in Windows, batch file/program]. This program searches for information relating to the keywords offered. Since the call in question used the -f switch, it searches for information about built-in Perl functions by the name "my". Then it displays the information found in formatted text. Use perldoc first to find out about perl keyword, functions, general question, modules, etc. > I went through a book , How to Perl > 5, last night.

It sounds like you are almost quoting the text. Try restating this in your own words. What you say here does seem to make sense, but what does it mean to you? Can you see the connection between scoping and the process of breaking programs into manageable chunks? As you work with these concepts, we will be happy to point you along the way. > > Well infact if u could send me a a small code which > uses the perl -f doc No. This is something you have to get in the habit of doing for yourself. You should get used to working at the command-line. It will be critical as you start writing and testing your code.
