You're almost there. As you say, unpack takes a string as its argument. If you supply an integer, then Perl quietly converts it to a (human readable) string for you, just as it does when do print 0; It 'ascii-ises' the number. In C terms, Perl does an itoa() on it. Conversely, when you pack the number, the string returned contains the machine readable, binary representation embedded within a string. In C terms, it is like doing:
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
