Re: developer 2000...global variables

Maybe using a parameter instead is better, but another solution is the use of 'DEFAULT_VALUE'. This creates a global variable if it does not exists yet, and assigns it a default value. If the global already exists, nothing happens.

So, write in your WHEN-NEW-FORM-INSTANCE trigger :

default_value('N', 'GLOBAL.DIRECTORY');
IF :global.directory = 'Y' then ...
