IIRC (but I may not remember correctly) SETPROG ADD can specify an 
alias.  However,

LLA is not Link list.

LLA REFRESH does not close, free, allocate and open the LINKLIST set. 
It re-reads the directory.

Think about it.  Stop LLA.  LINKLIST keeps on satisfying requests, 
albeit more slowly.  The system opened the LINKLIST set when the 
LINKLIST ACTIVATE was done.

Start LLA again.  If LLA is using different data sets than what are 
in the LINKLIST because you tried to outsmart the system, you will 
have errors.
