UPDATE			ON
			OFF

This command is used to prevent (or allow) database updating being carried out by a program.

UPDATE ON	This allows updating. This command will be ignored if the Natural administrator has made updating impossible during Natural installation.
UPDATE OFF	This prevents updating which would normally be performed as a result of an UPDATE, STORE, or DELETE statement. Programs containing these statements will execute normally but no modification of the database will occur. When an update operation is encountered, a message will be displayed instead of a database update being performed.

When the system command CHECK is used with UPDATE OFF, an error message is displayed. The UPDATE command has no effect on other Natural system commands.
