The DC and DP edit descriptors temporarily change the decimal edit mode for a connection.
These specifiers correspond to the DECIMAL= specifier values COMMA and POINT, respectively.
The decimal editing mode controls the representation of the decimal symbol during conversion of real and complex values in formatted I/O. It affects only D, E, EN, ES, F, and G editing.
Each descriptor continues to be in effect until a different decimal editing descriptor is encountered or until the end of the current I/O statement.
