We've got a mature body of code that loads data from files into a database. There are several file formats; they are all fixed-width fields. Part of the code uses the Perl unpack() function to read fields from the input data into package variables. Business logic is then able to refer to these fields in a 'human-readable' way. The file...

I have a Java program that spits out, in space-separated hexadecimal format, 16 bytes of raw packet received over the network. Since I dont want to change that code, I am piping the result to a Perl script that, theoretically, can simply unpack this from STDIN into recognizable variables.

I don't want to write a function for it, it should be...
A common 'Perlism' is generating a list as something to loop over in this form: for($str=~/./g) { print "the next character from \"$str\"=$_\n"; } In this case the global match regex returns a list that is one character in turn from the string $str, and assigns that value to $_ Instead of a regex, split can be used in the same way or ...
