Merged idea
This idea has been merged into another idea. To comment or vote on this idea, please visit IBMI-I-1461 Possibility to specify a compare procedure for SORTA and %LOOKUPxx.

SORT allow callback and ascending/descending multi fields for datastructure Merged

Multi field sorting was delivered with: https://ibm-power-systems.ideas.ibm.com/ideas/IBMI-I-2197


But this feature seems half-implemented because it doesn't allow ASC/DESC.... Please give the possibility to specify *ASCENDING and *DESCENDING when specifing multi fields. i.e.

OR

add the possibility to specify a procedure to call (callback), accepting two DS elements as parameters ad returning -1 (less) or 0 (equal) or 1 (greater) ... this would be the most elegant solution IMHO... like many other languages do for the "user" sorts....


DCL-DS array QUALIFIED DIM(3);
      id PACKED(5);
      name VARCHAR(10);
      type CHAR(2);
   END-DS;

   array(1).name = 'Alice';
   array(1).id = 34567;
   array(1).type = 'AB';

   array(2).name = 'Tom';
   array(2).id = 65432;
   array(2).type = 'CD';

   array(3).name = 'Alice';
   array(3).id = 12345;
   array(3).type = 'AB';

   SORTA array %FIELDS(name *ASC: id *DESC);

or

SORTA array %FIELDS(*CALLBACK sortmyarrayproc);
