A Session is a channel to the BDE. You can have multiple channels, and one
is opened as the default session when Paradox starts.
The default session can be accessed (settings) by the GUI interactively or
with OPAL, non default sessions can only be accessed by OPAL.

Some things are unique to that session, existing only in the session set
in, passwords, aliases, etc.

I think what you describe is true.


IMO, 99% of the time the use a of a non default session is not needed. I
have seen apps codes to use elaborate sessions where it was not needed.

It can be used to issue passwords not accessible to the main session, etc.
But since table level passwords are not secure... not sure if it is worth
it.

I open a form and add necessary passwords to access tables

I run a method and add password(s), then when the method finishes I remove
all passwords.

In what you describe using the default session (which you do not have to
open) is almost the same.

But, ff you close a non default session, it relinquishes (I think) all its
passwords and aliases, no need to know what was set and not set.

It would seem to me that if running a separate method requires its own passwords
then that is when I should add a session so I do not affect other passwords
already established.

Yes, but I am not exactly sure what you mean by "running a separate method
requires its own passwords"?
