IBM Mainframe Forum

Hi,

A cobol program that does internal sort on a variable length file throws a S0C4 abend in zOS v1.11, but runs perfectly fine in zOS v1.09
This has been identified by another team during their zOS upgrade. I'm curious to know about it, since my team will also be participate in one such upgrade soon. Sorry i dont have much details now.
Have anyone come across this issue??

Hello and welcome to the forum,

This most likely due to code that "got away" with something in 1.9 and now does not.

If they are not able to diagnose the problem, suggest they contact IBM or the vendor for the sort product.

There are a few million internal sorts running in 1.11 with no problems, so the problem is most likely the code.

Thank you, Master..

I'll post further on this when i get the details.

You're welcome - good luck

Someone will be here if there are discoveries that you would like to talk about.

It's sad, but true, that release changes often tease out real program problems because of altered storage maps. Most likely this is a problem with your Cobol program rather than a problem with your sort program.
