Which PDL changes force QDesign Recompile?

[Deskin, Bob]

Adding (or deleting) an ASC requires a recompile. So does adding or
deleting or changing a PERMIT, at least it requires a recompile of the
affected screen/run/report. The catch is that what's affected depends on
what security you had before. In other words, if you had other security
and you're just opening up this record to an additional ASC, then
recompiling the one screen should be fine. However, if you had no
security before, then adding a PERMIT affects all ASCs. Our default is
to allow access until it's restricted somehow.

The reason why it may appear to work is because of the way we handle
security internally. There are a series of flags the indicate whether an
ASC is allowed to access or not. In some case we initialize to on, in
some cases to off. If You add a PERMIT and the setting would leave it as
it is, then recompiling makes no difference in the setting. However the
reverse is true. Therefore, it's easier to simply recompile. How much
you need to recompile will depend on your other settings.

Thanks, Bob,
'logonids and the equivalent...'
Does adding a 'permit asc to read record blah'  fall into that? I need
to add an ASC permission to read a file and was wondering if I'd 
have to recompile everything or just the dictionary. I've added logonids

to an ASC without recompile, but never an ASC permission to a file.  I 
just tried it (i.e. created the new dictionary and attempted to access 
the file), and it seemed to work, but I didn't want to put the new 
dictionary out if it would cause problems with the rest of the users.

Thanks!
