You could write a subroutine record subroutine that calls system("/path/to/your/script") although that's a blocking call IIRC so it's not strictly legal in a database processing routine. It might be safer to do that from an SNL program, but there are actually many possibilities open to you between those two starting points and Pete's suggestion.
