    <p>My suggestion is to use <code>CALL</code> command. An example from <a href="http://www.robvanderwoude.com/call.php" rel="nofollow">Batch Files</a>:</p> <p>Batch1.bat listing:</p> <pre><code>REM Batch1.bat SET ABC=1 CALL BATCH2.BAT %ABC% ECHO ABC = %ABC% BATCH2.BAT %ABC% ECHO ABC = %ABC% </code></pre> <p>where Batch2.bat listing is:</p> <pre><code>REM Batch2.bat SET ABC=%ABC%%1 </code></pre> <p><hr /> <strong>EDIT:</strong> based on feedback from @Andriy M, here is an improved version for the two batches:</p> <p>Batch 1:</p> <pre><code>@ECHO OFF REM Batch1.bat SET ABC=1 CALL batch2.bat %ABC% ECHO 1. ABC = %ABC% CALL batch2.bat %ABC% REM test this line with CALL and without ECHO 2. ABC = %ABC% </code></pre> <p>Batch 2:</p> <pre><code>@ECHO OFF REM Batch2.bat SET tmout=5 echo sleeping %tmout% seconds... REM this introduces a timeout by using a nonexistent ip address PING 1.2.1.2 -n 1 -w %tmout%000 &gt; NUL echo done sleeping SET ABC=%ABC%%1 </code></pre> <p>See the line in batch1 where I wrote the comment <em>test this line with CALL and without</em>. Run that batch twice, with that line having <code>CALL</code> and without <code>CALL</code>.</p> <p>The output from console <em>without</em> <code>CALL</code>:</p> <pre><code>C:\temp&gt;batch1.bat sleeping 5 seconds... done sleeping 1. ABC = 11 sleeping 5 seconds... done sleeping </code></pre> <p>And now the output from console <em>with</em> <code>CALL</code>:</p> <pre><code>C:\temp&gt;batch1.bat sleeping 5 seconds... done sleeping 1. ABC = 11 sleeping 5 seconds... done sleeping 2. ABC = 1111 </code></pre> <p>Please note the difference: we get the 2nd echo, q.e.d.</p>

    1. COThat is to say, without CALL it waits just as well as with CALL, but only to… terminate. :)

    2. CO@Andriy M: Based on what I've experienced so far, that is **not** so, without CALL - execution returns immediately to the next line, without waiting for the called batch/command to finish (perhaps you should try that with long operations).

    3. COThat's so peculiar that I had to verify my expectation using your very sample scripts. I ran the first batch from command prompt in my Windows 7 SP1 and the two scripts worked for me just as I thought they would, i.e. the execution terminated after `batch2.bat` terminated when called the second time. That is, the last line of `batch1.bat` didn't execute. What have you tested them on that you are saying that without CALL the execution returns to the first batch, and without waiting too?

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.
