USPS Intelligent Barcode - binary data manipulationsby elfpen (Novice)
|on Sep 09, 2010 at 20:46 UTC||Need Help??|
elfpen has asked for the
wisdom of the Perl Monks concerning the following question:
I am looking at implementing the USPS Intelligent Mail Barcode algorithm in perl.
My first choice would be to find where someone has already done that, but no luck so far.
That leaves me with the need for some wisdom in handling a 13-byte data chunk that has both binary and decimal operations applied to it. Any advice?
Specification for the algorithm is at USPS Intelligent Barcode Page, then click on "Intelligent Mail Barcode Specification".
I have my implementation. It uses BigInt. It can be found at http://www.w0ep.us/IMBar.pl.
30-JAN-2011 found a bug in my implementation, uploading the newest to http://www.w0ep.us/IMBar.pl.
28-NOV-2011 another bug reported by a user. New version 1.4 as of today.
