Hello Mazhar It will help you a lot to know and use the documentation system of perl. You can get an overview by typing (on the command line): perldoc perl (docs) perldoc perldoc (documentation system) For your question with interpolatation, see perldoc perlop (and there "Quote and Quote-like Operators" and "Regexp Quote-Like Operators") For builtin funtions (here, the example is "q"): perldoc -f q Some questions are answered by perldoc -q your question or some word(s) of the question The online docs can be found at http://www.perl.org/docs.html Variable interpolation is expanding variable values into a string, done by double quotes (or qq). Think about the following code (run in from command line): perl -le ' use strict; use warnings; my $word=q{Tip: }; my @words=qw/ look at the docs /; print q($word @words), "\n"; print qq($word @words\n); ' btw, @04 is not a valid (array) variable name; they must not start with a digit, as not keyword/builtin does. Other tips: When asking questions, - choose an apropriate subject line - snip away irrelevant parts of the post HTH!
