Strings

Strings: sequences of characters, similar to Perl
  • double-quoted strings ("...") permit interpolation, e.g. 

    $x = 5;  print "Value of x is $x\n";
// prints "Value of x is 5"

  • single-quoted strings ('...') don't do interpolation 

    $x = 5;  print 'Value of x is $x\n';
// prints "Value of x is $x"

In "...", complex variables may need to be {...}
e.g. "The class member is {$obj->item}"
