	DBAG is a relational data base creation and maintenance system
.b
	It can be used in two ways
	-interactively, by commmands
	-in FORTRAN 77 programs written by the user
.b
	For users less familiar with the use of these types of 
command-based sytems, a menu-based interface is being developed.
.b
	DBAG is a multi-user system currently implemented on VAX/VMS
and soon to be adapted to the MS-DOS and UNIX environments.
.b
	The manipulation and editing of commands, records, etc. is done with 
a unique interface that, with a few differences, emulates the Digital EDT 
editor. For users of this operating system, the time to adapt to 
interactive DBAG will be greatly reduced .
.b
	Finally, note that user-written FORTRAN 77 programs can invoke 
a library of subroutines that permit any manipulation
of records or groups of records. As a matter of fact, the interactive system 
itself is nothing more than a program that uses this same library.
