The GT.M Global Directory Editor (GDE) is a utility that enables you to create, examine, and modify a global directory. GDE is a program written in M and you can invoke it from the shell with $gtm_dist/mumps -run ^GDE, with the gtm alias gtm -run GDE, or from inside the direct mode with Do ^GDE.

	The input to GDE can be a text file. In a production environment, FIS recommends using text files to define database configurations, and putting these text files under version control.

MUPIP CREATE uses a global directory to create new database files. At other times, the global directory is used only to map global variable names to database files. So, if you change the global directory, the database file is not changed and vice versa.
