Database Names and Locations Within HP ALLBASE/4GL, you must use a valid HP ALLBASE/4GL name for each database. You define this name on the database definition screen, where you also identify the external name of the HP TurboIMAGE/iX database (the name of the database root file). HP ALLBASE/4GL uses the HP4TIPATH system variable to identify the default account and group of each HP TurboIMAGE/iX database. You may specify a fully qualified name for the external database name on the database definition screen (that is, a name in the form FILE.GROUP.ACCOUNT). If you don't use a fully qualified name, HP ALLBASE/4GL uses the current value of the HP4TIPATH variable to search for the database at run- time. If HP4TIPATH is not defined, HP ALLBASE/4GL searches for the database in the user's current logon group and account. An HP ALLBASE/4GL application can access multiple HP TurboIMAGE/iX databases, anywhere in the MPE/iX file system. You may place these databases in the group and account defined by the HP4TIPATH system variable. For any databases that are not placed in this group and account, you must specify the fully qualified name of the database when you define it in HP ALLBASE/4GL. An application must be granted access to an HP TurboIMAGE/iX database before it can access the databse. You specify access to each HP TurboIMAGE/iX database for an application on the parameters for database access screen. On this screen you must also specify the user class password that the application uses to access the database For more information about granting an application access to a database, refer to Chapter 4 .
