# JMDash Argument Handler

The **JMDash Argument Handler** library is **JM-**'s way to handle arguments parsed at program's startup,\
and can be included in a **JM-** Project using: `#incd .jargh` 

If something isn't clear about the syntax shown below, we recommend you to check out the [examples category](/jmdash-docs/examples/code-examples.md)

## Syntax & Examples

`.jargh` : Common use cases, and syntax examples;

{% code lineNumbers="true" %}

```c
// Check if any arguments were passed on startup
#incd .jargh
bool areThereArguments;
arg.chk{>> areThereArguments};
```

{% endcode %}

{% code lineNumbers="true" %}
