The Catalog entry is in the VVCR not the other way round.  The DELETE NOSCRATCH 
merely causes the dataset to be uncataloged.  The VVR for that dataset is still 
intact.  The DEFINE RECATALOG must catalog the dataset back in the same BCS as 
it only has the VVR in the VVDS for information.

>From the AMS for CATALOGS manual

RECATALOG
Recreates the catalog entries if valid VVDS entries are found on the
primary VVDS volume..... 
Catalog entries can be re-created only in the catalog specified in the VVR
except for entries that are swap space, page space, or SYS1 data sets.

Also the ALIAS defined in the Master CATALOG would Relate the dataset HLQs to a 
specific BCS (Usercatalog).

Wouldn't the DELETE NOSCRATCH mark the VVCR as not in a catalog and available 
for RECATALOG? Otherwise we couldn't RECATALOG to another UCAT or must it 
always be recataloged to the original catalog?
