Delete observation within a variable if between a given interval : <p>I have a database with 3 variables:</p>

<p><code>Var1  Var2   var3</code> </p>

<p><code>A      10      20</code> </p>

<p><code>B       2      20</code> </p>

<p><code>C      -3      20</code> </p>

<p><code>D      1      20</code> </p>

<p>I want a general command that drop (omit) any observation if -1

<p>Any help?</p>
