From where is the WTOEXIT loaded? Steplib? CDMSLIB?
If linked with IDMSUXIT CV will attempt to load IDMSUXIT from STEPLIB if it resides there (see 18.5 PTF RO60928 which implemented this change).
If not in STEPLIB, CV loads IDMSUXIT from CDMSLIB.
If Not linked with IDMSUXIT and client codes WTO=wtoexit loadmod name in startup parms, the named module is loaded from CDMSLIB.
