Explanation
Critical. The invocation parameter list passed
to DFSORT using ATTACH, LINK or XCTL contained the eyecatcher C’PL64SORT”,
identifying it as a 64-bit invocation parameter list.   However, an
error was found in this parameter list. 
rsn 
is the reason code associated with the error. The reason code helps
you determine the specific cause of the error. Reason code values
(rsn) are as follows:More than one AMODE flag was set for a single exit in the 64-bit
invocation parameter list.  For example, the AMODE 64 and AMODE 31
flags were set for an E35 exit.
The AMODE flag set for an exit in the 64-bit invocation parameter
list does not correspond to the actual AMODE used by that exit. For
example, the AMODE 64 flag was set for an E35 exit, but the E35 exit
uses AMODE 31.
Zeros were not present in the 64-bit invocation parameter list
where required.  For example, a reserved field was not set to zeros,
or the high order word of an address was not set to zeros.

System action
The program terminates.

Programmer response
Take the action for the indicated reason
code value (rsn) as follows:Ensure that only one AMODE flag is set for each exit in the 64-bit
invocation parameter list.
Ensure that the AMODE flag set in the 64-bit   invocation parameter
list for each exit corresponds to the AMODE actually used for that
exit. 
Ensure that zeros are present everywhere they are required in
the 64-bit invocation parameter list.
