The override features of both the DFSORT OPTION and DEBUG control statements, when supplied through different sources, require special handling when EFS processing is in effect and either or both control statements are requested by the EFS program.

Because of these override features, DFSORT cannot simply send the OPTION control statement supplied in SORTCNTL and not send the OPTION control statement supplied in the extended parameter list. For the EFS program to process all possible operands on the OPTION control statements, DFSORT must send the OPTION control statements supplied in both SORTCNTL and the extended parameter list. DFSORT will send both the OPTION and DEBUG control statements supplied through different sources. If duplicate OPTION or DEBUG control statements are supplied in the same source and the OPTION or DEBUG control statements are also supplied in different sources, DFSORT will send the first occurrence of both the OPTION and DEBUG control statements supplied through different sources.
