    <p>Thanks to everyone for contributing to this answer. I am adding this answer to distill out the parts of everyone's invaluable input that I used to come up with the solution that worked for me in my particular application.</p> <p>The app is written in ActiveState Perl using POE and Tk and packaged for distribution using pp. It makes use of several external files; some for input into the program (munged data from DNS) and some for actions taken by the user (creation and deletion of DNS alias records).</p> <p>The PAR packer (pp) includes external files using the -a argument. These files are unpacked into the \inc directory under a "temp" path created by the package and available to the script via </p> <pre><code>$ENV{PAR_TEMP}</code></pre> <p>The first step in the solution was to add this information to the POE "$heap". The line below is in the in-line state "_start";</p> <pre><code>$heap->{t_path} = "$ENV{PAR_TEMP}\\inc\\";</code></pre> <p>As I am working in the Win32 environment, I used the escaped backslashes to append the \inc directory into the temp path.</p> <p>When calling an external file for input into the application, I used a variable (@zone) to return the data;</p> <pre><code>@zone = `$heap->{t_path}dnscmd aus-dc1 /enumrecords company.pvt @`;</code></pre> <p>For calls to complete external actions, the files are called without saving the output;</p> <pre><code>`$heap->{t_path}cpau -dec -file $heap->{t_path}del_event.job -nowarn -wait`;</code></pre> <p>Thanks again to everyone for contributing and thanks to stackoverflow for providing this great environment.</p>

    1. COuse `File::Spec->catfile( $ENV{PAR_TEMP}, 'inc')` rather than messing with double backslashes. By the way, I am a little surprised that I am the only one who has upvoted any answers in this thread: The way you show appreciation on SO is by upvoting answers.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
