Portal Scripts: A Stack Implementation

This trigger implements a basic corpse trigger

1. Bring up the Variable Maintanence dialog (@ on the toolbar)
2. To start you will need to create 2 variables, one for the stack and one for the "pop'd" value. Create your variables, and set the initialzation to Clear on Login for this example I will use @stack1example and @stack1pop.
   
3. Create 3 new aliases.
   STACK.PUSH
   STACK.POP
   STACK.INIT
   
4. Lets start with the easist first STACK.INIT this will initialize the stack.
   set(@stack1example=)
5. Next we do STACK.PUSH this will place the $1 argument on the stack.
   set(@stack1example=$1;@stack1example)
   Note: I am using the ; character as my delimeter
6. And Finally STACK.POP. The only way I can handle this at the moment is to pop the value into a variable
   set(@stack1pop=copy(@stack1example,1,pos(;,@stack1example))) set(@stack1pop=delete(@stack1pop,pos(;,@stack1example),1)) set(@stack1example=delete(@stack1example,1,pos(;,@stack1example)))

Now you have a basic functioning stack for use in other events or aliases.
