Oddly - DSORC correct all tables BUT the SU one.  The latter has an 
unusual name for the source number column and uses SOURCE for the 
character-valued name rather than the number so it needs to be treated 
differently.  It also misses an NX table now that ALLTAB does not copy 
one.  Fixed all these things.
