Dictionary Lists
Alright, here we go: Dictionary lists!
In programming (for those of you who don't know) dictionaries are lists with "keys" and "values". Each value is obtained by using its key. For example,
Foo: Bar
Hello: World
My dictionary has the value "Bar" at the key "Foo". You can also use numerical keys, like so: (this would help with backwards-compatibility)
1: Foo
2: Bar
3: Baz
Now "Baz" is at "3" and "Foo" at "1". So how would this help? I've come up with a few examples.
1. RPG-like inventories
Users could create inventories with keys being the items and values the quantities, like this: (click to enlarge)
2. Lists of unique strings with prices, data, etc.
Users could create lists of unique strings (the keys) with data (such as prices) as the values. For example, here is a small receipt program (in which I spelled receipt wrong):
Note: the reason I have code is because these examples are real, live, working code in a mod.
No more searching/looping through lists to find an item! Just use its key!
New users also wouldn't have to use this functionality as they can use purely numeric keys.

Re: Dictionary Lists
WHEN IS THE MOD RELEASED?!?
Maybe if Panther becomes stable enough, we can use this for Armour RPG...

Re: Dictionary Lists
Cool, but you could probably just use 2 lists

Re: Dictionary Lists
Interesting idea! It's really confusing, though - I don't think new users would understand that well.
Besides, what I do right now to achieve the same effect is to use two lists; one for indexing and another for the actual list content. It's not that hard, and it's simple enough for new users to understand.

Re: Dictionary Lists
GREAT idea. I can see so many uses! Although, I do agree with coolstuff on that.

Re: Dictionary Lists
omg you have NO idea how many times I've wanted this. Actually, this should be pretty easy to implement in my private mod... *starts hacking*

The glass is never half full nor half empty; it is twice as large as it needs to be.

Yep. That's pretty much it!

In that case, while I don't see a whole lot of use for this, it could be rather useful and make projects using this sort of system easier. So I give my support.

It'd be perfect for cryptography, like saving passwords in an OS. You could have a cell labeled 'a' and it's value would be 'b' so that in a string to be encoded, you could find the value in the dictionary list for each letter.

Re: Dictionary Lists
To be honest, I really want 2 dimensional arrays in Scratch, which would be slightly more helpful than this though...

Yes, but it is possible to make a list act like a 2-dimensional array.
Anyways, all you have to really do to allow dictionary lists is turn the cellMorphs variable in ScratchListMorphs into a dictionary instead of an orderedcollection.

Re: Dictionary Lists
Do you have the changes? Can you post them?

Yes, and then add support for that with numberMorphs (have to be completely redone) and all the ops need to be changed and some added, and you need to do a bunch of other thing I forgot...
Oh, yea: you need to make it backwards-compatible. I did this by automatically decrementing numerical indices (above n) when you delete one.

I could really use that.
