Hello I come from a small code that worked in prior to the last one released by the author of mIRC version, only now this command crashed and I do not understand why?

This is the code:


And now when I do the command: /nick (my nick) gives error

Someone can help me solve this?
Thank you

This is an intentional change, but the next version of mIRC will revert back to the old behavior because this is really breaking some scripts, more about it here https://forums.mirc.com/ubbthreads.php/topics/246559/Error_recursive_call#Post246559

Thanks very much for your help
