Its me again. I'm playing on a mud in which you have to visit a place and then remember it in order to portal/gate there later on. So I devised this ingenious system of aliases and triggers to allow me to add comments to the output from the mud that shows me the locations I have memorized.

It works really well, actually. Until I log out and close zmud. Then somehow *all* my arrays dissapear. The really bizzare thing is that my normal variables are still there and with the same values they had when I logged out.

Is there something in zmud that flushes arrays? Should I not attempt to use them for long term storage? I don't know how easily I could change it to work on a normal string var system. I suppose I could use a data record var, but anyways.. Here's the code in case anyone's wondering:

use:
rlset ## comment

This is why we don't use arrays except for when dealing with COM objects. Arrays are not saved beyond the session they were created in, and it's intentional (I dunno why, but it is). If you want it to save, use stringlists. Stringlists have about 50 times more support, they save to the settings files, and they look exactly the same as arrays.

Record variable is the way to go since you have a 2 dimensional array. The change over is quite simple and I will do it on one section, and let you figure out the rest.

#class Spells
remember set "%1" "%-2"
#if ("%2" =~ "%a") {rcomment = "%-2"} {rcomment = "Blank. Try using rset num comment"}
#if ("%1" =~ "%d") {
rnum = "%1"
#if ((@rnum < 10) and (@rnum >=0)) {
#ADDKEY rloc1 {@rnum} {@rcomment}
#show %ansi( white)Slot @rnum Comment added as:%ansi( under, White)%db(@rloc1, @rnum)
remember
}
}
rnum = ""
rcomment = ""

Hey, thanks again guys. And thanks Vijil for your code bit. That actually helped me hopefully as much as you figured it would. :D

Now that I understand that zmud's db thing is almost exactly like perl's hashes I can finally toss all my vars into them. Just for the heck of it I tossed together a proper a speedwalk manager thing, works well. Almost wanna add a field for extra info. Wonder how fun the databases are to play with :)

Now, can I create a data record of string lists (perl HoA/Hash of Arrays)? That would be add lots of fun to my eclectic collection of scriptybits. :)

Record variables can contain string lists, I suggest not using the . notation with most complex record variables. Although I have never really thought of a use for it you can even structure the record to have lists in the key names.

The actual database is a bit different to work with. Zugg wrote it himself very early in zMud's creation. There simply were no good database solutions at the time. You can do many similar things with indirect references. For example my script to ID equipment checks to see if the database is active and available. When it isn't it it creates a variable with a name based on a time stamp, stores the entire ID record there and records the variable name in a list. Later they are retrieved by using @{%item(@PendingIDs,1)} so it is possible to create mini-databases without actually using the database.
