In most other computer languages, you can create variables that hold all sorts of data, such as character strings, numbers, and so on You normally do this by declaring a variable name and then stating what type of data the variable is going to hold For example, the command

bugs, particularly when you re dealing with numbers (Not that you would ever have several versions of a variable called x , of course!) In WML, variables are both good news and bad news The good news is that they re very simple to use The only type that they can be is character They re easy to declare, and they re easy to assign values to The bad news is that any WML variable is global to the entire WML environment What this means is that if you use the variable x to store a piece of data in one deck, and then use the variable x in another deck to store another piece of data; when you go back to the first deck, a variable x will now contain what was entered in the second deck The really bad news is that this will apply even if the second deck was written by somebody else, or belongs to some other application altogether What this means to you, as the developer, is that you have to make very sure that you initialize all variables correctly when they are needed, or in the deck that they are needed, and that you keep your naming conventions consistent to avoid confusion There is an attribute of the card element called newcontext that will not only destroy all variables, but also the entire browser history The only time you might want to use this would be when you want to specifically ensure that the entire slate is wiped clean as far as the micro-browser is concerned But this, once more, is a last-ditch scenario, or something that you would put on the very first card of your application if you had to Even using it on the first card of your application is not a particularly good idea because you don t know how somebody has arrived at your application If you were a user who had followed a data trail to your application, and then you pressed the Back button and couldn t get back where you were before, would you be a happy user It is little things like this that make users wary of your application, or unwilling to return in the future Put yourself in the user s shoes and see how willing you would be to have something like this happen to you

The only thing you really need to know about using variables in the beginning is that variable names can contain only letters, numbers, or an underscore character, and they can only start with a letter or an underscore character So, for example, the following three variables are all fine:

To create, or set, a variable, you use the setvar tag The setvar tag only has two attributes name and value These are, simply, the name of the variable, and the value that

you wish to assign to it For example, the following creates a variable called test with a value of hello
<setvar name = "test" value = "hello">
In order to use this variable, all you have to do is prefix the variable name with a $ When the micro-browser finds a $, the variable name is simply replaced with the contents of the variable The only twist to this is when you want to use the $ as an actual currency symbol In this event, all you have to do is to type two $ $, and this will be interpreted as a single $ The setvar tag can only be used in a few places It can be used inside the go and prev tags, which we have already covered, and in a new one, refresh The refresh tag causes the variable assignment within it to be redone every time the card is displayed, and it is most commonly used for setting variables The refresh tag itself can only be used within an onevent or a do element Here is a very simple example:
<wml> <card id="main" title="Show Variable"> <onevent type="onenterforward"> <refresh> <setvar name="var_name" value="Mr King"/> </refresh> </onevent> <p> Welcome to my application, $(var_name) </p> </card> </wml>
