Before SMS, newly allocated data set that have not been opened for OUTPUT didn't have an EOF mark written and the attributes in the DSCB were only those from the JCL. With SMS, the EOF mark is always written, however, the system cannot know what attributes a program would add (override) to those specified in the JCL *if* the program does not actually OPEN the data set. And I believe it still holds true that DCB information is only stored in the DSCB if the data set was open for OUTPUT (and has actually had WRITE operations against it). This has been discussed in the past.
