I'm not using a db... just using #addkey to create "variables" with key->value pairs.
(like a perl hash)

I'd like to return the keys with a matching value and dump that into an array. But, everything I'm finding seems to return the value by key or requires the use of a db. Am I missing something? Suggestions? Advice?

I just realized, while it makes perfect sense to me, it might be a little cloudy to someone who doesn't know exactly what I'm doing... so here's a simplified example:

#Trigger {^Your (*) is (%w).$} {#AddKey Injuries (%1=%2}

Mud:
Your left arm is scratched.
Your right leg is bruised.
Your left big toe is gaping.
Your torso is bruised.
Your head is gone.

Now, @Injuries's value is:
left arm|scratched
right leg|bruised
left big toe|gaping
torso|bruised
head|gone

What I'd like to do from here is type "heal @prioritylimb" and assume my head will be glued back on first. Of course, if you're head's gone, you're going to want to treat that problem first. So, player would: "use healing head", "use healing torso", "use healing left arm", "right leg", ending with the big toe (as it can wait until the battle is over) whatever... (the order is the goal)

So, to help automate the healing decisions, I want to write a logic structure that, first checks for "gone" limbs, then "gaping", then "bleeding", then "scratched", then "bruised", while considering that some limbs are more important (torso vs left arm) ...

Bare in mind, this is a simplified example. Suffice it to say that healing doesn't solve the problem, completely, most of the time. Sometimes multiple applications may need to be used. Let's say my healing script uses the variable @prioritylimb... and I need to put the appropriate limb into that variable in the background so, when I have a chance to heal, I don't have to figure out which one is worst-off, I can simply heal @prioritylimb ... and count on my series of #IFs to have organized the array that feeds @prioritylimb, (let's call it:) @healorder, so that I can call on it quickly and reload @prioritylimb when I'm done healing (or satisfied with the current level of healing).

The problem is that I can't figure out how to call name of the limb based on its level of injury out of the "Data Record". I would want to heal all "gone" limbs first, then head and torso(whichever is worse off, preferably), then extremities (again, starting with worst-off).

... follow? good.
Help?

#loopdb @yourvar {#if (%key == "your string here") {do something nice}}

But really, depending on the size of your db, this is going to be slow, so if you're going to want to do this often you should change your variable so that it works more naturally. Maybe if you have a lot of keys and only a few distinct values, it would be easier to just keep them in stringlists to start with.

Edit: On reading further information, let me think about it for a while.

%isvalue

use healing %item(@db,%isvalue(@db,"gaping"))

I'd suggest making the process to add stuff into Injuries DB Var a little bit more complex.

Basically, you know for a fact the order in which you want to heal stuff.

So make a String List that will basically list things you want to heal, using syntax, say, "1_scratched" or something.

This list is made when you encounter some message which says that some body part of yours is hurt.
Into one String List you'd enter part that's hurt, into another one how it's hurt exactly.

#trigger {Your (%w) is (%w).} {#additem HurtPart {head};#additem HealStuff {001_gone}}

Now you'd have Event or Alarm or whatever which will become active when HealStuff has something inside of it.

Then it would sort the latter list, given that there are several places that are hurt, you can use %sort within script
or just tick the Sorted by Variable.

Then it'll be the question of healing stuff in turns, popping one off each variable while doing it

heal %pop(HurtPart)

When message it's healed is seen, you use same %pop with HealStuff variable

I have to think some more about it, because I think I understand what you're after.
You need to sort the values of the database variable and based on that add keys of the same db var into healing list, right?

I must say though, that I'm unsure how doable it would be under ZMud. Under CMud there are a lot of functions which
would serve purpose here though. Fang mentioned %isvalue, but there are also %dbvalues, %dbkeys and of course possibility
to use Local Variables which would do a large bunch of work here.

I'm going to think about it some more unless someone else comes up with an idea. But I have to say that there might not
be many ways to skin this one. Or maybe I'm just stupid because I haven't really coded for close to a year now.

Use %isvalue. It's simple, it works, and it requires no looping.

As it's already pointed out by OP, he mistakenly posted this as a CMud thread.

However, while scripting all this in CMud would definitely be very nice, I think I came up with some sort of idea how to solve your problem.

Imagine the above:

1) You have several triggers that add data to a DB Var, they're like this:
