Couldn't have said it better.  I use it also to "Mask" or "Define" the LDA.
To init the LDA,  Just have a program that defines the LDA D/S externally,
Do an "IN" of the LDA into that D/S and then do a RESET 'D/S Name'  and 
OUT the Initialized LDA.  

Now then, (Hans),  if (when compiling the program) they would bring in the 
DDS Default(DFT) values for the fields in that template file,  Then you
wouldn't have to hard code the INZ values for each field in the program!
