Dear Sven , 

                 Thanks for your suggestion. As per your instruction I add the brackets where ever necessary and corrected in my script .

 

In  gretl version 2023_b , the printf command ( with out brackets) runs and gives the results.

 

printf"------------------------------------------------------------\n"

 

This command does not show any error and got the results.

Yes, but your user syntax was still incorrect in this case. Sometimes it happens that it will work nevertheless, which is what I meant with "you got lucky". From time to time gretl (=its internal parser) will have to become stricter to avoid other unwanted side effects, and then those unsupported things may stop working. In these cases, it's not a bug of the new (stricter) version.

It's still good that reported this, we definitely want to hear about things that change from one release to another from a user point of view.

cheers

sven
