Hi Xie, This is due to the default value of special variable $" which is the separator used between list elements when an array variable is interpolated into a double-quoted string. Its default value is space. If you write $"="" before printing output will be v1v2v3 for both cases. Similarly $"="a" will print v1av2av3.
Thanks Sanket Vaidya -----Original Message----- From: xie ningde [mailto:n.d.ningde...@gmail.com] Sent: Tuesday, December 30, 2008 10:20 AM To: beginners@perl.org Subject: about "print" I'm a new perl user. I was trying to print an array by using print @array and print "@array". Is it supposed to output the same thing? I got the different output. EX: @array=qw/v1 v2 v3/, the output for print @array will be v1v2v3 while it will be v1 v2 v3 in the other case. The difference is one is seperated by whitespace while the other is not. Could anyone explain why this happen? Thanks alot. Cid http://www.patni.com World-Wide Partnerships.
