Re^2: Print unless behaving strangely

this or any other "invisible" problem could also be visualized with Data::Dump

use Data::Dump;

$_ = qq{PID: \0, VID: 255, SN: AGM163923J5};
dd $_;

"PID: \0, VID: 255, SN: AGM163923J5"

Thanks for all the replies, I will try to answer them all Yes I did mean "$_ contains the value 'PID: , VID: 255, SN: AGM163923J5". So this wasn't a section of the perl code. I am reading a file and it is at this line that strangeness happens. Yes I am using Strict and Warnings I have put the output direct from the Cisco CLI through a Hex translator and there doesn't seem to be any hidden/null characters PID: , VID: 0x500x490x440x3a0x200x2c0x200x560x490x440x3a but the output from the file perl is holding the string in does have extra characters. 0x500x490x440x3a 0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x2c 0x560x490x440x3a Thanks for all your help	[reply]

Yes I am using Strict and Warnings

I have put the output direct from the Cisco CLI through a Hex translator and there doesn't seem to be any hidden/null characters

PID: , VID:

0x500x490x440x3a0x200x2c0x200x560x490x440x3a

but the output from the file perl is holding the string in does have extra characters.

0x500x490x440x3a 0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x7f0x2c 0x560x490x440x3a

Thanks for all your help
