How do you alter the base eval scripts?

[LooseCannon]

I'm not a coder, so the scripting functionality seems a bit arcane to me. Nonetheless, I have a number of characters that make use of the In Debt negative quality. Is there someone in the community that is more savvy that could provide that script?

I posted the question here as it will require modifying a base script for maximum nuyen limit.

Thanks much in advance.
