Re: If a DCL-PI parameter has the LIKEDS(DSABC), and the data structure DSABC itself has DIM..

LIKE only copies the basic "shape" of the referenced item - it does NOT copy the dimensions of an array. This applies whether an array DS is referenced or a simple stand-alone array.

Of course, as part of the "shape" copy any _nested_ arrays DIMs are retained.

If you think about it, it makes sense. If you have a basic DS defined and want to use it as an array via a LIKE definition it is very useful to be able to use it to define arrays of variable sizes or indeed just a simple DS. I define such DS as templates with NO DIM on the DS.

I have searched the archives and the RPG reference and can't find the direct answer to this.

Will this work?

Does the DIM() follow are does it need to be specified as a parameter keyword?

DCL-DS ABCDS DIM(100) ;
ABC PACKED(3) ;
XYZ CHAR(3) ;
END-DS

DCL-PI GETARRAY ;
oABCXYZ LIKED( ABCDS ) ;
END-PI ;
