If you have PDM now, you possibly already have WDSC (or RSE or later). There are no similar size limits.
Note that the limit is in SEU rather than PDM. If you already have an alternative editor, why look for a replacement to purchase?
I realize SEU is the utility. The problem is I have a client who had EDITOR/400 and a month ago moved their outsourced operations from IBM to another 3rd party. Seems the licensing of the product didn’t like the move. The client asked me if I knew who the vendor for EDITOR/400 is so they could straighten out the licensing issue. And I do not know who the vendor is. Does anyone??
It wasn’t easy getting even this close, but it’s as close as I can get — Statement/400 Software Bv.
I haven’t seen evidence that the business is active nor that the product has been kept current. I’m not at all sure that the info will do any good.
