DING DING DING !!! WE HAVE A WINNER !!!

I do believe that is the single geekiest paragraph I have seen here. Congratulations!


(and please don't think my comment is in the least pejorative; it's purely complimentary!)

The computer industry tends to acronymize as much as possible as do other industries. I was in for 32 years, been out almost 6. I may not live long enough to lose it all.

APAR is Authorized Program Analysis Report. It is documentation that somebody notified IBM that something probably needs to be fixed.

Here is a nicely done little article about IEFBR14 in Wikipedia.

As a kid I wanted an Atari for Christmas as most kids in the neighborhood had one. My mom "researched" it and got me a TRS80 instead. It has the entry level 12k model and was not the top end 16k model. All of the good "radio shack" games were for the 16k model, and none of the other kids had a TRS80. My mom sent me to several programming classes/camps for the damn thing. Learned at any early age basic. All I wanted was to play frogger, et, pitfall, space invaders, etc......

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)
