RE: Possible SPAM: RE: Dynamic Variable Names in RPGLE

One problem with this idea....the user would have to have an exclusive
lock on the file(s) to add the constraint.  In a live production
environment this would hardly be feasible.  The most flexible way to do
this realistically in a production environment is through software
validation.  Use control table(s) that can be modified on the fly &
service programs,etc to perform necessary validation functions.  It
would STILL be a major pain to design, code & implement but it is a
do-able project. 


Thanks,
Tommy Holden

One radical way for the users to define their own rules might be through

ADDPFCST.  Write/update the record with the (e) extender and check for
the 
error.  I believe the file information data structure should be filled
in 
with the name of the constraint.  (name 'em, don't use system generated 
names).  I am not suggesting the users enter in the raw ADDPFCST command

but you handle that programmatically.
