Dear Gretl List Members,

There's a problem that appears with a considerable frequency here at
my work: To delete unused variables inside a Gretl session.

Please take a look at the .gretl file attached.

The variables "fora_de_uso", "fora_de_uso2", and "fora_de_uso3" (ID
numbers: 9, 5, and 18, respectively) cannot be deleted even though
they are not being used.

Why does this happen?

Best regards,
