Is VCSABEND a program written by someone at your site? If so, then you need to plan on debugging the problem yourself, or find who wrote the program and get their help. If VCSABEND is a program that is part of a vendor package, then you need to consult the vendor documentation to figure out the problem. In all cases, you cannot put responsibility for debugging the problem on this forum -- only someone working at your site can debug the problem, since your site is where the source code is, and where the dump is, and where the tools to debug the problem reside.
We on this forum can provide guidance if you are having problems with some aspect of the debugging process, but we cannot debug a problem, especially based upon the little you have posted. I STRONGLY recommend you contact your site support group and enlist their aid in debugging your program. You did not post much helpful data, and it appears from your reliance upon what Abend Aid told you that you have little to no experience in debugging, which is another reason to get help from someone working at your site.
