How to make bot ask questions only once

In aiml how to make bot answer questions like what is your name, your age, where do you live only once I did not understand this code

   <category>
<pattern>INQUIRY AGE</pattern>
    <template><srai>INQUIRY AGE <get name="age"/></srai></template>
    </category>

    <category>
<pattern>INQUIRY AGE HOW MANY</pattern>
    <template>How old are you?</template>
    </category>

    <category>
<pattern>INQUIRY AGE *</pattern>
    <template><srai>RANDOM PICKUP LINE</srai>
</template>
    </category>

Also from UDC

<random>
<li>INQUIRY AGE</li>
</random>

How to make bot ask these questions once?

Instead of using the <random> tag, you need to set a counter so the bot knows which question to ask and increase it each time. This will do it:

<category>
<pattern>ASK ME A QUESTION</pattern>
<template>
    <condition name="question">
        <li value="unknown">
            <think>
                <set name="question">1</set>
            </think>
            How old are you?
        </li>
        <li value="1">How old are you?</li>
        <li value="2">What is your name?</li>
        <li value="3">Where do you live?</li>
        <li>no more questions to ask...</li>
    </condition>
    <think>
        <set name="question">
            <map name="successor"><get name="question"/></map>
        </set>
    </think>
</template>
