This is rather ugly, you have a set of lookups for various values without correlation to structures, while the opening example does have problems of hash abuse with misspelling, I'd MUCH rather see field identifiers as constants and an HoH as a datastructure rather than having unaffiliated fields.

i.e. $records{$person}{$K_AGE}

That way you keep records grouped. Since Perl doesn't have real structures of any merit, the next logical step is to go to an OO representation and use functions/etc (maybe one of those MethodMaker deals) to prevent accidental typos.

At minimum, the Hash::Util method provides locking while preserving the logical representation of the data (edit: and clean Data::Dumper dumpability!).

Keeping fields seperated without context, IMHO, is the worst thing you can do.

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.
