This Natural profile and session parameter determines the character to be used as decimal separator, that is, a point or a comma.

Possible settings	any special character	The character assigned to DC will be in effect for all notations where a decimal separator is possible; that is, variables, constants and edit masks. The character specified with the DC parameter must not be the same as the one specified with the IA (input assign character) or ID (input delimiter character) parameter. In addition, we recommend that this character is not the same as the one specified with the CF (control character for terminal commands) or HI (help character) parameter.
Default setting	. (period)
Dynamic specification	yes
Specification within session	yes	Applicable statements:	SET GLOBALS	Parameter is evaluated at runtime.
		Applicable command:	GLOBALS	Parameter may be specified dynamically with the GLOBALS system command.
Application programming interface	USR1005N	See SYSEXT - Natural Application Programming Interfaces in the Utilities documentation.

Notes:

1. Within a Natural session, the profile parameter DC can be overridden by the session parameter DC.
2. If you change DC in your parameter file, you must resave the DDM you are using in your Natural program which stores a new .NSD file on disk.
3. Under Natural Security, the setting of this parameter can be overridden by the Session Parameters option of the Library Profile.
