<div class="markdown_content"><p>Oh, now I understand. The question is since it was an AND condition and the first vlaue is false that means why even evaluate the second. Missed that one.</p></div>

<div class="markdown_content"><p>Hi, I'm asking something about condition evaluation. Check the following code:</p> <div class="codehilite"><pre><span></span><span class="nv">var_a</span> :<span class="o">=</span> <span class="nv">FALSE</span><span class="c1">;</span> <span class="nv">var_b</span> :<span class="o">=</span> <span class="nv">FALSE</span><span class="c1">;</span> <span class="k">if</span> <span class="nv">var_a</span> <span class="nv">and</span> <span class="nv">var_b</span> <span class="k">then</span> <span class="nv">begin</span> <span class="c1">;//Some code</span> <span class="k">end</span><span class="c1">;</span> </pre></div> <p>In this case, did the program will check the var_b or it will bypass directly after checking the var_a value ?</p></div>
