Dear Gretl List Members,<br><br>There&#39;s a problem that appears with a considerable frequency here at<br>my work: To delete unused variables inside a Gretl session.<br><br>Please take a look at the .gretl file attached.<br>

<br>The variables &quot;fora_de_uso&quot;, &quot;fora_de_uso2&quot;, and &quot;fora_de_uso3&quot; (ID<br>numbers: 9, 5, and 18, respectively) cannot be deleted even though<br>they are not being used.<br clear="all"><br>Why does this happen?<br>

<br>Best regards,<br>-- <br>Henrique C. de Andrade<br>Doutorando em Economia Aplicada<br>Universidade Federal do Rio Grande do Sul<br><a href="http://www.ufrgs.br/ppge">www.ufrgs.br/ppge</a><br>
