Four Essential FROM Parameters

The four FROM parameters that take part in all transactions are shown in Figure 1. They are:
  • The FROM parameter. This begins the FROM section. It tells BDT that the parameters that follow describe the “from” data set.

    BDT assumes that any parameter that is not a job definition parameter and is not in the TO section is a FROM parameter. Therefore, you only have to include the FROM parameter in your transaction if you list parameters describing the “from” data set after the TO section of your transaction.

  • The DATASET parameter. This parameter identifies the data set to be copied. The format of this parameter is DATASET(ds-name). Substitute a data set name for ds-name. You must include this parameter in your transaction.
  • The LOC or LOCATION parameter. This parameter identifies the node at which BDT is to find the “from” data set. The format of this parameter is LOCATION(node-name). Substitute a node name for node-name. You must include this parameter in your transaction unless:
    • You are in a single-BDT system and the data set is at your node
    • You are in a poly-BDT system and the data set is at the node that is defined as the default for your installation.
  • The DAP parameter. This parameter specifies whether BDT is to use the PDS or SEQ dynamic application program (DAP) to copy the data set. The format of this parameter is DAP(dap). SEQ is the default for this parameter.
    • To use the SEQ DAP substitute SEQ for dap or omit the DAP parameter.
    • To use the PDS DAP substitute PDS for dap.

    You may put the DAP parameter in either the FROM or TO section of your transaction.
