Re: Calling BPXWDYN to Return DSNAME for DDNAME

[David Staudacher]

"Setting R0 = 0 is essential!" Unless you have this APAR fix installed: 
http://ibm.com/support/docview.wss?uid=isg1OA51807 - "OA51807: NEW FUNCTION - 
BPXWDYN ALTERNATE ENTRY POINT BPXWDY2 FOR HIGH LEVEL LANGUAGE PROGRAM CALLERS"
Then you can call BPXWDY2 instead of BPXWDYN.
