WA CA 7 Edition
CA 7 will assign an index value of 255 when you use the /JCL command to dynamically to add a JCL library (even if JCLDEFS=VSAM is specified in the RESIDENT statement). If a specific index ID other than 255 is needed for a JCL library, it can not be added dynamically. You must manually add a JCL statement in the CA 7 initialization file for the desired INDEX=nnn value and recycle the CA7ONL started task to apply the change.
