ICE183A

Explanation
Critical.  The indd DD statement and outdd DD statement
both specified the same VSAM data set, but one of the following conditions
prevented  DFSORT from using the same VSAM data set for input and
output: The application is a copy or merge
NOVSAMIO is in effect
NORESET is in effect
The VSAM data set is not defined with REUSE

System action
The program terminates.

Programmer response
If you want to sort the VSAM data set in-place,
ensure that VSAMIO and RESET are in effect, and that the VSAM data
set is defined with REUSE.  Otherwise, ensure that the indd DD and
outdd DD statements do not specify the same VSAM data set.
