  1. $myroom->{$room}->{r}: $myroom contains a hash reference. The "->" operator dereferences it. $room must contain a hash key. {$room} uses the key in $room to index into the anonymous hash referenced by $myroom. $myroom->{$room} contains another anonymous hash reference. {r} indexes into that 2nd level anonymous hash.
  2. (/l: (.+)$/i): This part: /l: (.+)$/i is a regular expression. It says to match "l: ", followed by one or more characters, excluding newline. Capture those. And this all must occur at the end of the string. Case insensitively.
  3. Assign the value of 0 to the variable $system. Assign the first value captured in a regexp to $Proom. Assign the second value captured in a regexp to $cDept, after "upper casing" it.

Read the following: perlintro, perlretut, perlrequick, perlreftut, and uc.

Update: I see you have 21 posts here to PerlMonks starting in June. So perhaps my interpretation of your question was more basic than what you were asking. If so, I apologize and request that you be more specific in your question. And if not, then please read the documents I linked to. :)
