Please oh please: use DIRMAP iso DISKMAP. DIRAMP knows how to properly treat fullpack minidisks, they are not taken as overlap... In my CP directories, **any** overlap signals a problem, there should be not a single one, otherwise people will miss a truely unexpected overlap too. DIRMAP even signal overlaps with a non-zero return code and message to the console, but, it ignores fullpack overlays. With DIRMAP fullpack definitions are still a very good thing, for example to learn DIRMAP how many cylinders a volume has; no need to define a dummy user $END.
