Data area
The third fullword in the parameter list is the address of a fullword that contains the address of a data area.
A data area consists of the actual data involved in the request. If you are retrieving information from a database, EQQYCOM places the record in this area and provides its address in the fullword whose address is in the parameter list.
If you are writing information to a database, your program must build its own data area and provide its address in the fullword whose address is in the parameter list.
The data area consists of a header, which describes the structure of the data record, and the data itself. For a detailed description, see Data area description and format.
