Yes, this is what I have done and it works well. Since I only need information from the first volume (RECFM, LRECL, DSORG, etc.) the combination of TDJCB/X'13' and OBTAIN got me what I needed.
I still need to do OBTAIN before the DD is first opened in the step in order to get the DSCB info. Otherwise the JFCB returned by RDJFCB contains only DSN and DISP for an existing dataset, which was the target here. Thanks for the help.
