The following posts are based on this tutorial which was included in a previous release of PicoLisp. Opening and Writing to a Database file Let's start with the basics: opening and writing to a database file. We can do this from the REPL ($ pil +): ...

How do we set val to {2} as was set to {1} as "Hello World"? In the blog, (default) val of {2} is NIL.

Hi Nehal, I'm not totally sure what you mean by that, so excuse me if my answer is a little bit off!

First of all, you can set any external symbol ({1}, {2}, {3}, ..) like this: (set '{2} 123)

However, this is more suitable for debugging mode because except than debugging, you do not know the external symboll for each data has.

And note that {1} has a little bit special role because it is the root of the database, this is why you can set the value via the *DB global variable.

Let me know if you have more questions, this topic is really a little bit hard to explain&understand in the beginning.

Hi Mia Temma, hope you've been good. Thank you for responding on previous blogs too. Glad you could come over.

My fault actually. I didn't type a quote. 😐 And was getting NIL - - Protected.
