That's the reason why I programmed "modal-like" until we had
private datasession. Apart from always keeping all tables open
or writing Your own very very complex Table-handlers, using
private datasessions is the only way to make this bulletproof.

Using private datasessions is very simple (just set the forms'
Datasession-Property to 2-Private Datasession) and causes every
form (more or less) to behave like an isolated workstation in a
network. There are some minor traps You might fall into but
nothing severe.

If You have subsequent form-calls (i.e. form1 calls form2) where
form 2 should use the data of form1, You can leave the Datasession-
property of the second form in its default-setting. The second form
will be in the same datasession as the first one. Both together
protected from the outside world.

Just have a look at the SET... settings (SET CENTURY, SET DECIMALS
etc.). Some of them only work for the current datasession. So You
might have to set them for each form You call. But that can be
done via a global procedure.
