Could anyone please help me to understand what exactly is RC=39.
VSAM ERROR RC=39
IGZ0020S A logic error occurred. Neither FILE STATUS nor a declarative was specified.
The OPEN statement was unsuccessful because a conflict was detected
between the fixed file attributes and the attributes specified for that
file in the program. These attributes include the organization of the
file (sequential, relative, or indexed), the prime record key, the
alternate record keys, the code set, the maximum record size, the record
type (fixed or variable), and the blocking factor.
