foreach interation over specified index values in multiple index arrays

[Mike Mason]

I have an array with two indexes.  I'd like to use foreach to iterate over part of the array by specifying the first index value and iterating over the second index (see example below).  Is there a way to do this?  Nothing I've tried works.

Thanks,
Mike

global arr

probe begin
{
        arr[0,0] = "00"
        arr[0,1] = "01"
        arr[0,2] = "02"

        arr[1,0] = "10"
        arr[1,1] = "11"
        arr[1,2] = "12"

        arr[3,0] = "30"
        arr[3,1] = "31"
        arr[3,2] = "32"

	// stap doesn't like the 3 in foreach
        foreach ([3, idx2] in arr) {
                printf("%s\n", arr[3, idx2])
        }

        exit()
}
