The fundamental difficulty of displaying/presenting the concatenation sequence goes to the heart of program fetch and DEB management in general. The mapping for a concatenation consists of a series of track extents for input I/O; VOLSER identity is not part of the map.
Not sure I agree with this. The DEB extent entry doesn't list the volser per se as a 6-byte character field, but it does have the 4-byte UCB address which is even better because with that you can find out not only volser but every else about the unit...
