Re: FORMS4.5 (PASSING GLOBAL VARIABLES)

There may be scenarios where it is possible to try to use a global that hasn't been created.

To avoid this use the default_value built-in.

default_value('X','global.my_var');

If the global exists default_value does nothing otherwise the global is created with the value of the first argument. Note that the global is in quotes NOT :global.my_var.
