Spock: How to run a set of methods as a single test repeatedly?

I have a set of defs (methods) for test automating in web. Each def represents a single page's actions. I need to pass parameters in some pages in the middle of the process. Using where block in a single def resulting iteration in the same def and does not proceed in the next def.

How I can pass parameter in the middle of a test?

Example:

def "A"
{
}

def "B"
{
}

def "C"
{
where:
    param1 << value1
    param2 << value2
    param3 << value3
    param4 << value4
}

def "D"
{
}
and now loop again from def "A" for the next set of parameter?
