- Contain the actual data
- Address the actual data
When the Eyecatcher field contains 'IRX8' and the Level field contains a value of 1, there is one element format, which either contains the data or addresses the data. New development should use only a Level of 1; a value of 0 is deprecated. These elements are described by the following figure.
- Inline format contains data.
- Pointer format addresses the data.
Inline Method
The element type field in the Element header indicates whether the parcel body will follow the header or a pointer element will follow the header. For information on setting Inline and Pointer methods, see Element Type.
If Eyecatcher is set to 'IRX8' and Level field is set to 0 in the extension header (D8CAIRX) or if the Eyecatcher is set into 'DBCX' in Extension header (DBCAREAX), the following is format in which the parcel is sent in Inline method.
If 'IRX8' with level 0 is used, then the structure defined for this purpose is 'D8XILMNT'.
If 'DBCX' eyecatcher is used, then the structure defined for this purpose is 'x_element'.
Pointer Method
If Eyecatcher is set to 'IRX8' and Level field is set to 0 in the extension header (D8CAIRX8), the following is the format in which the parcel is sent in the Pointer method.
The structure defined for this purpose is 'D8XILPTR' and is available in dbcarea.h.
If Eyecatcher is set to 'DBCX' in the extension header (DBCAREAX), the following is the format in which the parcel is sent in Pointer method.
The structure defined for this purpose is 'xp_element' and is available in dbcarea.h..
