Function Calls in Strings

           print "Next year, I will make $SALARY*1.06 dollars\n";

           print "I have wallet_contents('pebbles') pebbles in my wallet.\n";

• Why do beginners expect these to evaluate?

• Because lots of stuff is evaluated inside of strings:

           print "Element 3 is $s[3]\n";

           print "Roses are $color{Rose}\n";

           print "The one you must kill is $data->{People}{Enemies}[$i].\n";
