How do I use the not operator with variables? [SOLVED]

Stillman

Suppose $wrench can have many values throughout the game: "held", "hidden", "lost", "broken", etc.

I want something like this: <<if $wrench is not "held">>You don't have the wrench.<<endif>>

I ran some tests to no avail. Is there a way to do this, or at least a list of things the not operator will work on? Without not, I'd have to make a rather complicated <<if>>:

<<if ($wrench is "hidden") or ($wrench is "lost") or ($wrench is "broken") or ($wrench is "in trunk") or ($wrench is in "in puddle")>>You don't have the wrench.<<endif>>

If the mods are reading, the wiki could do with more examples than the sole visited() one presented.

What you're looking for is:

<<if $wrench neq "held">>

There's a list of operators on the twine wiki. Uhh, the link is http://twinery.org/wiki/expression down at the bottom.

Thanks. I just find the examples in the chart there too terse. For instance, how would you use their 'not visited("Waterfall")'  with an <<if>> or <<set>> or whatever is allowed?

Like so:

<<if not visited("Waterfall")>>the player has never been to the waterfall<<endif>>

Since visited() actually returns an integer, you could also do that as:

<<if visited("Waterfall") is 0>>the player has never been to the waterfall<<endif>>

Or:

<<if visited("Waterfall") eq 0>>the player has never been to the waterfall<<endif>>

I see. Thanks.
