Re: Exported Variables (was Long Constant Names)

This is one of the reasons I would like to have an option to define
prototype variables and data structures. The prototype variable would
only be used by the compiler as a reference for variables defined LIKE
the prototype. The prototype wouldn't be associated with any memory and
would not be allowed to be used outside the D specs.

When I need to use LIKE to define a field, but don't want the field/DS
to take up memory, I define it as...

      *===============================================================
     d lercdds       e ds                  extname(LTREDTA)           
     d                                     based(@)                   
     d                                     qualified                  
      *===============================================================
     d #rtvedta...                                                    
     d                 pr                  like(lercdds.ledata)       
     d  company                            like(lercdds.lecomp)       
     d                                     const                      
     d  service                            like(lercdds.leserv)       
     d                                     const                      
     d  rectyp                             like(lercdds.lertyp)       
     d                                     const                      

This is stored in a copy member.  I can also use LIKE in the procedure
interface to define the parms in the procedure, as long as I don't use
those fields in an embedded SQL statement (still at V5R2).

As long as I don't assign a value to the basing pointer (I use the
at-sign as a pointer that will NEVER be assigned storage), no memory is
assigned.

One way, anyway.
