Code:
mob/verb
    test()
        new card_handle(src,src)
    deck()
        world<<src.hand




mob/var/hand[]=new

card_handle
    New(mob/player1,mob/player2)
        world<<"lawl"
        var/list/deck=new
        for(var/obj/card/c)
            deck+=c
            world<<"added [c]"
        while(player1.hand<8)
            var/p=pick(deck)
            deck-=p
            player1.hand+=p
            world<<"player one has recieved: [p]"
        while(player2.hand<8)
            var/p=pick(deck)
            deck-=p
            player2.hand+=p
            world<<"player one has recieved: [p]"
        //Now that all is set up, both players have 8 cards, we can begin\
        our crazy eights game! Time to start up the turns.
        turn_start(player1,player2)

Problem description:

I decided to make a crazy eights card game, I wanted to mess around with lists. However I am unsure of how to run a datum. Is calling New a good way of starting one up? I seem to get errors attempting this.

EDIT: I do know what a datum is.

(some of the coding is still not complete)

Create datums like you would any other atom.
new/card_handle(src,src) //create a card_handle datum with src being player1 and player2
//just like
new/obj/pickles(src) //create a pickle in your inventory

You can't "run a dantum". There is no such thing as a dantum, and a datum is able to be considered a thing. I personally consider them concepts of things, like a party, etc. You run a proc; New() is a good way to call one procedure, as is doing it manually if you have more than one thing to do.

I already tried executing it with new datum() but it failed. Something to do with a list. Unfortunately I'm not exactly sure why. It only runs the first test message after a mass of "red errors" in the game, indicating that something is wrong. Maybe I'm just doing something wring with me lists?

_>. It's called a type path. datum != a type path.

EDIT: /datum is the type path.

This_Is_A_Datum
      New()
            world << "You made a datum. I bet it took ages to figure this out, eh?"
mob/verb/Datum() new /This_Is_A_Datum()

I know that already. I knew all of that. >_>

I actually initially had it exactly like that. It's only not like that because it wasn't working.

That "red error" is called a "runtime" error.
You need to read these, and you can find what the problem is.

You are comparing a list to an integer. (player.hand<8)
I imagine this should return a runtime error for comparing a non-integer to an integer.

Ah, so I should be checking hand.len is greater than 8. Thanks.
