Ditto, but I had no choice. Besides, Marna suggested it. :-)

Based on the comments in that section of code ("start of work area cleared
in converter sub-task initialization"), I think CIWJSCHE. Although it
probably doesn't matter for finding the SCHENV. From reading the
APAR text of OA42098 (which had about 20 different fixes rolled in),
it looks like CIWSCHE was just added for convenience as one of
the "common actions" being dealt with in exit 6/59/60.
MG18933 - The JCT pointer in the converter DTE (DCNVJCTA) has
been restored. Also, the DCNV mapping of the
converter parameter list (R1 on entry) has been
restored as a separate DSECT. Finally, the most
common actions in exit 6/59/60 have been embodied in
the XPL parameter list, namely set the job class, set
the scheduling environment, and hold the job.
