Re: Are level checks still useful?

I'd better repost that hyperlink, since the last one included an unwanted space:

PHP/MYSQL people scratch there head (more like point fingers at 

me and snicker) when we struggle with level check.

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!
