Would not the alluded issue(s) only be possible for the reverse; i.e. if using Check Out Object (CHKOUT) then ensure an eventual Check In Object (CHKIN) is also performed? AFaIK there is no ill-effect from performing a check-in of an object that is not checked-out; the CHKIN request does not even fail when the specified OBJ() is not checked-out, and merely should be ineffectual, much like a DLCOBJ [similarly for which any ALCOBJ should be followed with an eventual DLCOBJ, although locks disappear with the end of the process, whereas IIRC the status of checked-out persists even across pwrdwn\IPL sequences.?

Compared to the other options presented, this offers the most
opportunity for trouble.

While I agree that the all too often suggested use of CHKOUT as a /trick/ to test existence [or any other purposes, other than actual intent of effecting a Check-Out of the object] should be discouraged, I am unaware of any problems with using CHKIN *except* if the user might have legitimately performed a prior CHKOUT for which the effect of CHKIN [without their knowledge nor intent] that might be undesirable.
