TSO/E REXX LISTDSI providing information out of the VIO datasets

We have legacy jobs using LISTDSI to collect dataset attributes; SYSNAME SYSDSORG, SYSLRECL and SYSRECFM. We want to increase the default maximum size of the VIO storage group to benefit batch workloads. Before the VIO increase their temporary datasets were allocated in DASD and their code using LISTDSI worked fine. We tested the increase of the VIO storage group size, after the increase their temporary datasets got allocated in VIO and their code using LISTDSI failed with return code 16. Replacing the LISTDSI command with new code retrieving the dataset attributes out of JFCB data area in legacy applications would not be easy.

Bottom line LISTDSI should provide the dataset attributes out of the VIO allocations.
