having trouble with this aiml code

when I log out of a chatbot then talk to her again she will forget what she had learned.

Yes, that will be a new conversation.

To access global variables you need to use Self.

i.e.

<self>#self.like =+ star</self>

will my chatbot remember what I taught her the next time I speak to her with this aiml script?

how would I use self in aiml to access global variables?

<category><pattern>I like it when *</pattern>
<template>Is that what you always liked?  <think><self>#self.like = star;</self></think></template>
</category>
<category><pattern>what do i like</pattern>
<template>You like <self>#self.like</self></template>
</category>

would this allow me to change what I taught her I liked to do?

I need it to store the last weekday I talked to my chatbot.

it works.i can change what it learned with this.
