EXIT /B 1 GOTO :EOF </code></pre> <p>The whole script could use some better error checking, examples of what not to do or where error checking is a bit wonky:</p> <ul> <li><code>dl foo.txt 1-2-4</code> (prints lines 1-2 but no error message)</li> <li><code>dl foo.txt -1</code> (error message that the range 1- isn't correct)</li> </ul> <p>Other limitations:</p> <ul> <li>Ranges must be sorted. With the current implementation there is no way to do something like <code>dl foo.txt 7-8,1-2</code>.</li> <li>No line may be selected twice. Something like <code>dl foo.txt 1,2,2-8,11-15</code> will stop after the second line.</li> <li>No support for UNIX-style line endings (U+000A)</li> </ul> <p><strong>EDIT:</strong> Fixed an issue with files that contain parentheses.</p>

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.
