Batchfile: What's the best way to declare and use a boolean variable? : <p>What's the best way to declare and use a boolean variable in Batch files? This is what I'm doing now:</p>

<pre><code>set "condition=true"

:: Some code that may change the condition

if %condition% == true (
    :: Some work
)
</code></pre>

<p>Is there a better, more "formal" way to do this? (e.g. In Bash you can just do <code>if $condition</code> since <code>true</code> and <code>false</code> are commands of their own.)</p>
