## Permanent Vs. One Time Options

“undada” lets you control every aspect of the parsing in the same way the Project Configure dialog does in Understand for Ada’s GUI. One important difference is that with “undada” options can be permanent or just for the invocation of “undada”.

Here is the rule: Any option specified when creating a database will be permanently stored as an option to be used with future uses of “undada” (unless overridden or reset using the Understand for Ada GUI).

So...

    undada -db foo.uda -create_95 -comment never

permanently causes comments to not be associated with definitions, while

    undada -db foo.uda -comment never

uses that setting only for this invocation of “undada”.
