Explanation
MIX or MIXS was specified together with EGCS'hh'. The MIX or MIXS value has priority over the EGCS'hh' value.
System action
IMS ignores the EGCS value, and uses the device default.
Programmer response
If the DFLD statement defines an EGCS or a DBCS/EBCDIC mixed field, either correct the keyword and rerun the job, or accept the device default value.
