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 ...

There was a tip on Linkedin last night for people who are struggling with file level checks. It seemed to be worth considering, so I wrote a small program to test the idea. This is a program that performs setll, read, write, update, and delete operations against a table:

With this structure, no file level checks are reported at runtime even though the file is defined with LVLCHK(*YES), new fields have been added, using alter table, the program was NOT recompiled, and it seems to run flawlessly.

Thoughts?

Record layouts and key layouts are externally defined, too. Nice!
