Yes indeed. The DSNames would not be those of the original DDDEFs, but
of the UCLIN REP[laced] ones - after a cloned CSI has been updated to
point at them.
E.g.
//SMPCNTL DD *
SET BOUNDARY(GLOBAL)
.
UCLIN
.
REP DDDEF(SMPPTS)
DA(<whatever the cloned SMPPTS new HLQ
is>.SMPPTS)
SHR
.
DEL DDDEF(SMPLOG)
.
ADD DDDEF(SMPLOG)
SYSOUT(*)
.
ENDUCL
.
<etc.>
