RE: %Scan (Again...)

["Nicolay, Paul" <paul_nicolay@xxxxxxxxx>]

Hi Barbara,

I just opened a problem report if that is of any help.

As far as the 'needle' is concerned... why not return 0 as well ?

Kind regards,
Paul

Paul, I agree that when haystack is empty, %scan(needle:haystack)
should just return zero, without an error.  (Although I think it should
continue to give an error when needle is empty.)  You are right, this
_is_ annoying - by coincidence, I just ran into it yesterday.

Without an APAR, I can't promise a PTF for this.
