Re: Defining datastructure with ExtName/LikeRec

I believe you can use QUALIFIED with EXTNAME, so there's not much difference
in functionality. The newer way is to use LikeRec, but it's only really
better if you have record formats which have different *INPUT and *OUTPUT
fields (as with display file records, for instance). I always use Extname,
since I need to recompile code back to V5R1.

LikeRec will make your data structure qualified. Off the top of my head
I'm not aware of other differences in the resulting data structure.

Subject: Defining datastructure with ExtName/LikeRec

Dear list,



I'm defining a datastructure and I want the layout of the datastructure
to be the same as an existing file.



Now I'm a bit puzzled. What do I use ? ExtName or Likerec ?



dsMyFile E DS ExtName(MyFile)

or

dsMyfFile DS LikeRec(MyFileR)



And what is the difference between ExtName and LikeRece ?
