Learning Perl on Win32 Systems by Randal Schwartz, Erik Olson, and Tom Christiansen Here are the changes made in the 7/99 reprint: {56} Used to read: (1.2 .. 5.2) # same as (1.2, 2.2, 3.2, 4.2, 5.2) Now reads: (1.2 .. 5.2) # same as (1, 2, 3, 4, 5) {56} Used to read: (1.3 .. 6.1) #same as (1.3,2.3,3.3,4.3,5.3) Now reads: (1.3 .. 6.1) #same as (1, 2, 3, 4, 5, 6) {93} The code was incorrectly changed in the 4/98 reprint to read "l" (letter el) instead of "1" (number one): changed it back. Here's how it now reads (letter L capitalized only to emphasize it): $a =~ /(.)\1/; # also true (matches the double L) {214} Used to read: www.microsoft.com/msdn/sdk Now reads: http://msdn.microsoft.com/developer/sdk/ Microsoft has renamed the 'Active Messaging Library' the 'Collaboration Data Objects (CDO) Library', which can be found at http://msdn.microsoft.com/library/ --> Platform SDK --> Messaging and Collaboration Services
