Purpose: The CREATE DBL command establishes and declares a Data Base Library, which is the primary organizational and control object of an ACCENT R application. All other ACCENT R objects are recorded in the central application repository of the DBL. See Section 3, Volume I, of the ACCENT R Professional Desk Reference Set for a full description of Data Base Libraries.
CREATE DBL name
|
is
the user-assigned name of the Data Base Library established with this
command. For the syntax of DBL names, see Section 2, Volume I, of
the ACCENT R Professional Desk Reference Set. The default extension
is .DBL. When a DBL is created, it becomes the current DBL. The
USE DBL command is not required.
|
NOTES: A DBL must not be renamed or changed outside of the ACCENT R system, for it would then be unrecognizable by ACCENT R.
The CREATE DBL command both creates the Data Base Library and declares it as the current DBL.
Once a DBL is declared, any subsequent USE DBL command automatically closes the current DBL and all open Data Sets and Data Indexes before the next DBL is declared.
If a REMOVE command specifies the current DBL for removal, ACCENT R sets the USE NO DBL condition. If the current DBL is renamed through ACCENT R, ACCENT R recognizes the new name as the current DBL.
