This was implemented in #49? No?

Yep. Can you test?

A language constant None equates to 0

>a=None
NO RETURN VALUE
>a
0
>a==0
1

Is this desired behavior? I think this works, and introducing a null-like type at the moment may cause a lot more work in the language than it just equating to 0.

Otherwise, yes None works.

I wonder if I committed the correct files.
Here's what I get:

<HyPhy Base Object>
>a=None
NO RETURN VALUE
>a
<HyPhy Base Object>
>a==0
...error message...
<HyPhy Base Object>

The error message is about Attempting to operate on an undefined value; this is probably a result of an earlier 'soft' error condition Exiting...

Ok. It looks like I pulled from upstream on a different server and forgot to do so on my own machine. This makes more sense now.

However, I do get this:

>a=None
NO RETURN VALUE
>a==None
0

Shouldn't it equate to 1?

Good call. Just fixed and pushed the mods to veg/hyphy.

Verified. Closing issue.
