# call — Call function

CALL breaks out of the current control flow and continues with the execution of a function. It then returns to its original control flow. Arguments may be passed to local variables as parameters on switch of context.

A function can be coded so that it may call itself recursively. This technique allows direct implementation of functions defined by mathematical induction and recursive divide and conquer algorithms.

### Attributes
| Name | Type | Default | Description |
| ---- | ---- | ------- | ----------- |
| func | var |  | Function variable name |
| var | var |  | Result variable name |
| var_params | var |  | Variable name for associated parameter name and value pairs |
| var_this | var |  | Variable name for explicit rebinding of 'this' |

### Children
- (none)

### Parents
- (not restricted in the reference)

### Result
- binding: var; type: n/a
