  At some point in time, the CHGVAR was enhanced to enable access 
directly to the *LDA for both set and get [using the %substring builtin 
function].  I do not see any *LDA support in ADDRESS() parameter of the 
DCL [declare variable], so I do not know if\what data type capabilities 
CHGVAR could give beyond enabling using CHGVAR; i.e. simply removes the 
requirement to use RTVDTAARA, and the same substring issue remains.  It 
would be possible to declare typed data directly over the storage using 
a BASPTR [basing pointer] if the CHGVAR could use the %ADDR() to get an 
address to the *LDA.  Presumably not possible, neither by CHGVAR &PTR 
%ADDR(%SST(*LDA 1 1)) nor %ADDR(*LDA) since %ADDRESS() builtin function 
apparently only supports a CL variable name.

Documented for %sst it is suggested that one may "code *LDA in place of 
the character variable name to indicate that the substring function is 
performed on the contents of the local data area."

  The above on\by v5r4.  I am not sure about any more on 6.1
