U0850 is a user abend code. Check your shop manual for that.

Type "QW" at command line and place your cursor on the abend code and press ENTER... If your shop has Quick Reference, It'll show up all messages related to U0850.

Hi Priyesh,

After analysis i found that some other program is trying to update the segment while my program is reading that..... I think this is the reason for the U0850 abend..

I have one question...what happens when one program is reading the segment and the other program is updating the same segment simultaneously ? Will the read program waits until the update program completes its task..or the read program reads the old copy...

I dont know whether i am putting the question in the right manner...Please let me know if you are not clear with what i am mentioning.
