Does CA JCLCheck scan the entire DD concatenation for data set existence before checking if a program or member exist?

JCLCheck will first validate if all the datasets exists in the DD concatenation and issue CAY6079 messages for the dataset that do not exist and do not check for program or member existence since it is incomplete.  Only when it is confirmed that all dataset exists will it search the entire concatenation for program or member existence.
