RE: LVLCHK(*NO)

["Tom Liotta" <thomas@xxxxxxxxxxx>]

Also FWIW, LVLCHK(*NO) really shouldn't be an issue if the application is 
designed decently and modified later appropriately.

For most files, is there good reason to have more than a single program access 
the physical file? If access is through appropriate logical views with explicit 
field lists, then physical files can have fields added easily, at the end, 
beginning or middle. Just recreate the LFs and there are no level checks except 
for the single program that accesses the physical file. Only the single program 
needs to be recompiled (or run as LVLCHK(*NO) but I couldn't recommend that).

Naturally, I realize that existing applications can have trouble; but I thought 
the original question was forward-looking.
