This is how I would start, but I'd need more complete spec

#!/usr/bin/perl -- use strict; use warnings; use Data::Dump; my $rawAsHex = q'0001000000004f914f1c0b0100425343413030000000050000434 +130303030300000000143413030303134000000024341303030323200000003434130 +3030323400000004434130303032390000000100224e43656c6c30000000020042534 +341303100000005000543413031303031000000064341303130303400000007434130 +31303130000000084341303130313500000009434130313031360000000100224e436 +56c6c30000000030042534341303200000006000a'; my $raw = pack 'H*', $rawAsHex; my @stack = unpack q{ A2 ### Header Record Id : 1 Byte A2 ### File Format Version : 1 Byte A16 ### Timestamp : 8 Bytes A2 ### No. of BSCs : 1 Byte ### For each BSC ...

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
