Question concerning "Grid control"

I'm having a problem with screen SAPLSLVC_FULLSCREEN.0500 (Display PM Orders : List of Orders). 
My problem is how to read the screen with an InputScript. 
It displays a list of Work Orders and I need to go into the Display Maintenance Order screen (SAPLCOIH..3000) for each order, to retrieve some data. This works for the first entry, but how do I move down the list, as GuiXT sees it as X[GRID1] rather than a table?

I suggest you use GuiXT Controls and its "Native Control Interface". This interface is covered in a separate section in our Tips, Tricks & Samples.
