# Passing data values to a macro-step #
Macro-steps as defined in the _Basics_ section are pretty limited.
Remember Joe and his calculator?...
Suppose that Joe created a macro-step as follows:
```cucumber
...
Given I define the step "When I [enter the number 8]" to mean:
"""
When I type 8
And I click Enter
"""
...
```
While being a perfectly valid macro, it is almost useless since it will always enter the same digit 8.
What Joe really needs is a macro-step that allows him to enter any number.
His wish, in turn, implies that the previous macro-step should accept one parameter value: the number to enter.
Here is how Joe might proceed:
```cucumber
...
Given I define the step "When I [enter the number <some_number>]" to mean:
"""
When I type <some_number>
And I click Enter
"""
...
```
And here is how he can use the last macro to enter the value 2:
```cucumber
...
When I [enter the number "2"]
...
```
## Rules of the game ##
When a macro-step is required to take one or more values, then:
1. Place in the step being defined the name of an argument between chevrons < ... >.
2. When the macro is used in a scenario, place the value of the corresponding argument between double quotes "...".
