Relax requirements for using Ds in I/O

The general problem is about the compiler issuing a RNF7595 when I try to use the same Ds (or Likerec Ds) on diffent files sharing the same format and based on the same PF.

This is an example:

Dcl-f fileA01L keyed usage(*input);

Dcl-f fileA02L keyed usage(*input) rename(FILEA:FILEA2);

Dcl-ds filea02 extname('FILEA02L') qualified inz(*extdft) End-ds;

Dcl-ds filea02R likerec(FILEA2);


chain X FILEA02L filea02; // Ok no errors

chain x FILEA01L filea02; // RNF7595

chain X FILEA02L filea02R; // Ok no errors

chain x FILEA01L filea02R; // RNF7595


FILEA01L and FILEA02L share the same format and are based on the same PF.


Relaxing the rules would be very useful to reduce the number of definitions and eval-corr operations like in this example:


If y=1;

chain x FILEA01L filea02R;

ElseIf y=2;

chain x FILEA02L filea02R;

ElseIf y=3;

chain x FILEA03L filea02R;

EndIf;

if %found();

// Use a common logic based on the Ds filea02R.

EndIf;
