The dpkey struct is used to pass the parsed contents of DPja or DQia keyrecords to disset() via the disprm struct. A disprm struct must hold only DPja or DQia keyvalues, not both.
All members of this struct are to be set by the user.
| char dpkey::field | 
(Given) The full field name of the record, including the keyword name. Note that the colon delimiter separating the field name and the value in record-valued keyvalues is not part of the field name. For example, in the following:
the full record field name is "DP3A.AXIS.1", and the record's value is 2. 
| int dpkey::j | 
(Given) Axis number (1-relative), i.e. the j in DPja or i in DQia. 
| int dpkey::type | 
(Given) The data type of the record's value
| int dpkey::i | 
| double dpkey::f |
