Re^2: Binary conditionals

C. So, $buffer == hex ('0x00') would match if, and only if, $buffer == 0, hence, if $buffer contains the character "0".

Sorry, I have to disagree:

$ perl -wle '"a" == 0 && print "yes"'
Argument "a" isn't numeric in numeric eq (==) at -e line 1.
yes

So you see that 'a' == 0, and when you have warnings enabled, you also get a warning.

Right. And this is why the OP complains that too many characters match (but not every character). $buffer==0x0 is true for every char except '1' to '9'. Rule One: "Do not act incautiously when confronting a little bald wrinkly smiling man."	[reply]
