RE: Long Constant Names

["Bob Cozzi" <cozzi@xxxxxxxxx>]

You mean you want a read-only variable?

     D FN              DS                  Qualified
     D  Acro                          3A   Inz(*Blanks)
     D  Chunk                        21A   READONLY Inz('FILES/DOCTRL3')

I use constant fields for a few things, commands strings I intend to
use for system() commands, and all literals I intend to use and not
modify at runtime.

What I was asking for was the ability to create a data structure, with
certain elements that remained constant. i.e.

     D FN              DS                  Qualified
     D  Acro                          3A   Inz(*Blanks)
     D  Chunk                              Const('FILES/DOCTRL3')

The second component of the data structure should never change.  In my
mind, it should be declared constant.
