The following table explains how Fetch-data-pointer works in Locate-mode (Locate-mode = 'Y').
| If you set Parcel-mode-fetch in DBCAREA to this value... | And you set Varying-length-fetch in DBCAREA to this value... | Then the address in Fetch-data-pointer points to the... |
|---|---|---|
| Y | N | first byte of the parcel body. |
| Y | Y | two-byte length field that precedes the returned data. |
| N | N | first byte of the buffer, which is the first byte of the parcel header of the first parcel. |
