Ok Basicly what I'm trying to is create a buddy list built right into zmud.

What I need is a way that the user to can add a person to a list of other people.

EX add player3 to buddy list
This would add a third player to a list of players.

The other catch is showing them on or offline. which would be done thru a trigger like
Inform: player 3 has entered Merentha.
or
Inform: player 3 has left Merentha.

How would i go about creating this list so people can easily be added/removed to it thru an alias or trigger, without overwritting all the previous information?

#ALIAS BudAdd {#ADDITEM BuddyList {%-1}

I am not really sure where your going with the online.offline thing as this is likely to require a method of first synchonising the list of online persons. After that you can simply trigger to #ADDITEM or #DELTITEM from the online list.

I'd use a datarecord variable and use #addkey/#delkey.

#variable buddylist {}
#trigger {Inform: (*) has entered Merentha.} {#if (%iskey(@buddylist,%1)) {#addkey buddylist %1 "online";Showbuddies}}
#trigger {Inform: (*) has left Merentha.} {#if (%iskey(@buddylist,%1)) {#addkey buddylist %1 "offline";Showbuddies}}

Then you can use an alias to show the buddylist in another window (I don't think you'd want to have it spam the main window):

#alias ShowBuddies {:BuddyListWindow:#clr;:BuddyListWindow:#say Buddies in Merentha;#loopdb @BuddyList {#if (%val = "online") {:BuddyListWindow:%key}};:BuddyListWindow:#cr;:BuddyListWindow:#say Buddies not in Merentha;#loopdb @BuddyList {#if (%val = "offline") {:BuddyListWindow:%key}}}

ShowBuddies will display all your buddies in two groups (those online, and those offline).

To add and remove buddies, you can use a couple aliases:

#alias AddBuddy {#if (%iskey(@buddylist,%1)) {#say This person is already on your buddy list!} {#say %1 added to your buddy list;#addkey buddylist %1 %2;Showbuddies}}
#alias RemoveBuddy {#forall %replace(%1," ","|");#if (%iskey(@buddylist,%i)) {#say This person is not on your buddy list!} {#say %1 removed from your buddy list;#delkey buddylist %i;Showbuddies}}

AddBuddy will only let you add one person at a time, while RemoveBuddy will allow you to remove multiple people at a time. Also, AddBuddy requires you to specify the status of the buddy to be added.

Very cool. Regreatably the remove buddies doesn't seem to work. it also does the show buddies even if it isn't a buddy that logs on.

I'm thinking you didn't copy the entire line for each trigger. Simply move the ShowBuddies alias from outside of the curly brackets to the inside like I had them:

#IF (condition to check) {
#ADDKEY stuff
ShowBuddies
}

If that's how it looks already, seems there's a bug with %iskey()

ok really stupid question. is their a code that can take a variable, record its value so so permenantly stored somehow but still allow the variable to change? kinda like if the varaible is a counting up. each time it goes up it saves the number somehow but continues to count up?

Or is it possible to have a variable store more than one value such as
a name, a number, and a word.

Yep, it's possible. It's called a stringlist, and it can be the value of a datarecord key. They're a bit harder to work with if you want information out of them, though.
