Provide common APIs in support of PDSE Member Generations - Part 2

See https://ibm-z-hardware-and-operating-systems.ideas.ibm.com/ideas/ZOS-I-3783 for part 1. Given that PDSE member generations are supported by some, and growing, IBM elements, it only seems reasonable to make it easy. Thus I'm rating this IDEA as...

RACF control to allow or disallow copying of data from an encrypted dataset to an unencrypted dataset

Today if a person has access to a key label there are no controls in place to limit their ability to copy an encrypted dataset to a dataset with no DFP segment in it's RACF dataset profile. When this is the case the dataset is unencrypted when wri...
