LOL - I do remember hearing something about that years ago. To think that IEFBR14 had a bug in it is priceless
Without Googling it, I'm going to take a wild ass guess from my ancient assembly days...
I'm guessing they had to add a "SR 15,15" statement to zero out the return code? (I hope I got my syntax right - been years, decades even, since I had to think about assembly)
