Re: Are level checks still useful?

Nathan:

Technically, this is a "program described" file, not an "externally 
described" file -- so I don't think the RPG compiler generates the code 
to initialize the UFCB in such a way that the "level check" will be 
performed (at open time).

As far as I am concerned, this "technique" is equivalent to telling 
someone to "Close your eyes and step on the gas!" while driving a 
car...  :-o

IMHO, you are just handing a loaded gun to some "programmers" so they 
can shoot off some of their own toes!

Good luck with that ...
