If the value provided is not appropriate for the application, perform the following steps before calling DBCHCL for the Connect, Run Startup, or Initiate Request function:

  1. Change Options to 'Y'.
  2. Set the Parcel Mode Fetch value to the appropriate value:
    • Y, if each fetch is to provide the next parcel (Parcel Mode Fetch set to Y is known as Parcel Mode).

    • N, if each fetch is provide the next buffer-full of parcels (Parcel Mode Fetch set to N is known as Buffer Mode).

If Buffer Mode is in effect, each fetch results in a new buffer-full of parcels. It is assumed that the application program has “consumed” the previous buffer-full of parcels.
