Changes Proposed

Issues addressed:
These parameters are actually optional, use default value if not provided.
So that we don't really need to enforce 0 for these fields if not required (example card fields 2 ~4)
However, if the fields that we wanted to customize a certain parameter, then all the parameters before it required to set value.

Instead of

@item2 5001 1 1 10 0 4001 0 0 0

we could just do these

@item2 5001
@item2 5001 1 1 10                     (refine only)
@item2 5001 1 1 10 0 4001              (refine + 1 card)
@item2 5001 1 1 10 0 4001 4002         (refine + 2 cards)
@item2 5001 1 1 10 0 4001 4002 4003    (refine + 3 cards)

hard to read changes.
probably you can split actual changes and style fixes into separate commits?
