# Variable Introduction
Variables are used to store various types of information and can simplify complex data into simple aliases. When invoking data subsequently, you can directly use the alias to replace the original complex content, simplifying process configuration.
You can customize and add new variable values in global variables, which can be directly called and reused when creating RPA tasks later. The global table supports creating multiple variables, including types such as text, number, boolean, time, link, and coordinate. Any fillable content can be used directly.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://doc.bitbrowser.net/cloud-phone/rpa-guide/guide-graphic/flow-designer/variable-introduction.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
