<h1>ISREF Function</h1>
|
|
<p>The <b>ISREF</b> function is one of the information functions. It is used to verify if the value is a valid cell reference.</p>
|
|
<p>The <b>ISREF</b> function syntax is:</p>
|
|
<p style="text-indent: 150px;"><b><em>ISREF(value)</em></b></p>
|
|
<p>where <b><em>value</em></b> is a value to test entered manually or included into the cell you make reference to.</p>
|
|
<p>To apply the <b>ISREF</b> function,</p>
|
|
<ol>
|
|
<li>select the cell where you wish to display the result,</li>
|
|
<li>click the <b>Insert function</b> <img alt="Insert function icon" src="../images/insertfunction.png" /> icon situated at the top toolbar,
|
|
<br />or right-click within a selected cell and select the <b>Insert Function</b> option from the menu,
|
|
<br />or click the <img alt="Function icon" src="../images/function.png" /> icon situated at the formula bar,
|
|
</li>
|
|
<li>select the <b>Information</b> function group from the list,</li>
|
|
<li>click the <b>ISREF</b> function,</li>
|
|
<li>enter the required argument,</li>
|
|
<li>press the <b>Enter</b> button.</li>
|
|
</ol>
|
|
<p>The result will be displayed in the selected cell. If the value is a valid reference, the function returns TRUE.</p>
|
|
<p style="text-indent: 150px;"><img alt="ISREF Function" src="../images/isreftrue.png" /></p>
|
|
<p>Otherwise the function returns FALSE.</p>
