# Recall

The printing of recall object output is controlled by entering "y" or "n" in the *recall* line in [print.prt](/io-docs/introduction-1/simulation-settings/print.prt.md). In addition, a basin average of all recall objects can be printed by entering "y" in the *basin\_psc* line in [print.prt](/io-docs/introduction-1/simulation-settings/print.prt.md). Recall object output can be printed at daily, monthly, yearly, and average annual time steps. The names of the recall object output files are as follows: 

* recall\_day.txt
* recall\_mon.txt
* recall\_yr.txt
* recall\_aa.txt
* basin\_psc\_day.txt
* basin\_psc\_mon.txt
* basin\_psc\_yr.txt
* basin\_psc\_aa.txt

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:

```
GET https://swatplus.gitbook.io/io-docs/swat+-output-files/recall.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
