previous examples. Then, <span class="cmdname">OVRDBF</span> commands are used to override

two local files named FILE1 and FILE2 with the local DDM file RMTCAR. When

an application program attempts to open the files, the DDM file DDMLIB/RMTCAR

member TEST1 and member *FIRST (the first member). This example requires

only one DDM conversation and one target job because both open operations
