If no function is being called, an empty string is returned.

## Method Signature

```
GetFunctionCalledName()
```

### Arguments

This function does not accept any arguments

## Examples

### getFunctionCalledName Basic Example

Show results of calling a function directly versus by reference

[Run Example](https://try.boxlang.io/?code=eJydjrEOgjAQhmf7FBdYYHJxkspi4qiLL3CWA5rUlpQrDMZ3V1A0Jp0c77%2Fv%2F%2FKLwekK6mAVa2cBFQc0h%2Fd5xCtlOdzEavSa6RS4C5xBEqVG7EGhMVQB9ltIG%2BKF2M%2Fxi0vlxZcJ5IW4i1%2BrbH0p20050do20S1y%2FQTmduxb%2FGGEQSN4qsmTVfT1f6KzWwqwixii5DTlAWJed%2FI%3D)

```java

void function actualFunctionName() {
	writeOutput( "actualFunctionName() was called as: #getFunctionCalledName()#<br>" );
}
writeOutput( "<hr><h4>Calling actualFunctionName()</h4>" );
actualFunctionName();
writeOutput( "<hr><h4>Calling actualFunctionName() via reference</h4>" );
referenceToFunction = actualFunctionName;
referenceToFunction();

```

### Getters and Setters Example

Example of using getFunctionCalledName to create dynamic getters and setters

```java
//callednamedemo.bx
component
{
    variables.x1 = 1;
    variables.y1 = 2;

    function init() {
        return this;
    }

    function get() {
        var name = getFunctionCalledName();
        return variables[mid(name,4,len(name)-3)];
    }

    function set(value) {
        var name = getFunctionCalledName();
        variables[mid(name,4,len(name)-3)] = value;
    }

    this.getX1 = get;
    this.getY1 = get;
    this.setX1 = set;
    this.setY1 = set;
}

<!--- calledname.bxm --->

<bx:script>

	function test() {
		return getFunctionCalledName();
	}
	writeOutput( test() & "<br>" ); // test
	a = test;
	writeOutput( variables.a() & "<br>" ); // a
	o = new callednamedemo();
	// shows *real* methods get(), SetX1() and getY1(), etc.
	writeDump( o );
	o.setX1( 10 );
	o.setY1( 20 );
	writeOutput( o.getX1() & "<br>" ); // 10
	writeOutput( o.getY1() & "<br>" );
</bx:script>
 <!--- 20 --->
```

```java
yell = ( Any name ) => {
	echo( name );
	dump( var=getFunctionCalledName(), label="Function was called as" );
};
yell( "yell" );
say = yell; // copy function
say( "say from " );
yell = say; // copy function again
yell( "yell from say" );

# Agent Instructions: 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:

```
GET https://boxlang.ortusbooks.com/boxlang-language/reference/built-in-functions/system/getfunctioncalledname.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.
