Thanks. That worked. 

OK, thanks. That's very useful, of course, for finding simple syntax errors, such as a missing closed bracket. 

I'm basically just looking for something I can use on-the-go on my iPad Pro. On my Mac I continue to use BBEdit. So I'm looking for something as close as possible to BBEdit for iPadOS. 

I sure with there was a way of having a trial with iPad apps! :)

Thanks,
