According to the documentation, CIMTPARM Member HPOREORG should specify global parameters for FUNCTION=REORG and FUNCTION=BATCHREORG
Currently there is no way to distinguish between the parameters specified in the HPOREORG global parmlib member. Both the REORG function and the BATCHREORG function use this member. If you wish to specify parameters that are specific for either of the functions and do not apply to both, then you have to create a global parmlib library for each function, one for REORG and one for BATCHREORG.
I would like to request separate parmlib members for REORG and BATCHREORG.
