Accessing macro array elements

[Tony2]

Hi all

So I have a step which reads a file using a regex and matches 4 groups.
I have the option "Store matching groups in array"
And the macro it is going in is named DATABASE

If I log %DATABASE% to the output then I get 4 lines containing the information.
I need to be able to access each element individually so that I can run a command line putting the right elements in the right places....

How do I do this, I can't find anything on accessing a macro array in the help....

Thanks
