Re: using LikeDS on a subfield.

["Joe Lee" <LeeJD@xxxxxx>]

I don't have a ds02, I wanted to define d103 as a sub data structure
like ds02. And I don't want to hassle with overlaying the sub data
structure with a char field so that I can pass the overlaying field to
the procedure. 
 
There are lots of methods I could use to achieve the results I want, I
just thought that defining the subfield as a sub data structure using
LikeDS was the most elegant. Oh well, just another reason to look
forward to V5R2.

I must be missing something here. If you need to pass a data
structure,
couldn't you just pass ds02? (Sorry to be so dense. . .)
