# Variable invocation

Variable invocation is the act of referring to a variable's name in order to invoke its value.  

The variable invocation grammar is to be replaced with the value of the variable. 

## Grammar

A variable invocation is represented by the following grammar:

```
${VARNAME}
```

Where VARNAME is a valid variable that has been previously declared using the grammar specified in [variable-declaration](variable-declaration.md)
