@temp = "#VARIABLE bw_defense_enabled ~{%if~(~@has_bw AND ~@bw_defense_issued = 0,1,0~)}"
#EXEC {@temp}

yields:

#VARIABLE bw_defense_enabled {0}

How do I get around this?

(same results occur with local variable $temp instead of @temp when called from inside an alias)

0 is one of the possible values of bw_defense_enabled. If I create has_bw and bw_defense_issued and give them proper values, it works fine. If it's not working for you, it's possible that it's a scoping issue.

What I don't understand, though, is why you need to build the #var command in this way. There's probably a better way to do it.

I need the value to be %if(@has_bw AND @bw_defense_issued = 0,1,0)

@temp != @bw_defense_enabled, it's a string that's going to be executed to create the variable bw_defense_enabled through the #exec command. It'd help if I knew how it was going to be used because there's almost certainly a better way to do it. I assume the example above's deliberately contrived.

temp = "#FUNCTION bw_defense_enabled ~{%if~(~@has_bw AND ~@bw_defense_issued = 0,1,0~)}"
#EXEC {@temp}

is working. Note that you do not need the @ when you're assigning the variable. You could also use a local variable instead of a "real" one. You don't need to quote all the special characters in the string either - ~ and " are the only special characters inside a string.

EDIT: There might be a bug here, though, since

temp = "#var bw_defense_enabled ~"%if(@has_bw AND @bw_defense_issued = 0,1,0)~""
#EXEC {@temp}

isn't working.

OK, this is really getting messing, so it's time for me to chime in.

First, I have no idea why you are trying to do something this way. I think you should tell us what problem you are trying to solve in the first place. Whenever you start using #EXEC, you should usually be asking yourself if there is a better way, because #EXEC should be the last resort (it's the slowest way to do anything).

But back to your original post:

1) You should not be using the syntax: @temp = value. You don't put the @ character unless you are *expanding* the value of a variable.

2) There are some issues using ~" within quotes. In v2.0 I have fixed it so that you can just use double quotes "" to specify a single quote.

3) If you are trying to assign a function to vw_defense_enabled, then you should be using #FUNCTION (called #VARFUNC in v2.0) and not #VARIABLE.

So, I think your script should just be this:
