I was looking at Rosetta Code today and happened upon the Quine task, which inspired me to try to write one in ViviFire. I decided to use some features that I've considered but haven't yet implemented in the parser. If you all find this syntax agreeable, I'll probably add support in the next EXE release.

Brent,

These would all be great features!!

I would definitely change the #Null to #Debug though as I always think of the null character when I see something like #Null. #Debug would help to ensure that the user knows whatever comes afterward will be sent to an output of some kind. I assume you'll automatically detect if a (the) debugger is open and send it to that; otherwise I think you may need another variable to tell the language where the output is to be sent.

Just my thoughts on it....

I think that #null should be reserved to represent nothing or uninitialized.

#debug would be simple and understandable as triggering debug output.

Thanks for the comments. I just added support for the mentioned constructs. But then I discovered that my example has a syntax error.

The second line begins #null a$(0), which is parsed as a normal method call rather than the expected anonymous method call. After this, the parser expects a line break, but finds a + instead, causing the "oh so helpful" error -- line 2 col 12: this symbol not expected in Newline. I probably should do something about that.

The correct code follows.

What I still see as strange is the missing closing curly brace in the first line of code.
If this is the supported syntax, it is fully on the contrary to what one is used from other languages utilizing curly braces.

Stefan, the closing curly brace is represented by $125 which translates into LB as Chr$(125). The second line cannot contain any quotes, otherwise they'd need to be escaped in the first line. This makes the code simpler.
