Usage Notes

The Fetch Maximum Data Length field specifies the length in bytes of the Move area, if any, allocated by the application program.

If the application program is using Move Mode for processing the parcels in the response, that is, if Locate Mode is set to N and Parcel Mode Fetch is set to Y or N in the DBCAREA, then the application program must allocate the Move area and place its length in Fetch Maximum Data Length before calling DBCHCL for the Connect, Run Startup, or Initiate Request functions.
