This is an ISPF application written by C/C++. When I start it on one of my Mainframe environment, OC1 abend happens with the error something like ISPLINK error. See the attachment.

Is there anybody has seen similar error before? I want to know if this is possibly caused by environment setup or my C/C++ codes, such as there is null pointer kinds of mistakes. Thank you.

Yes, it is possible. In fact, I think it is likely.

1. check that the linkage editor or binder ended with RC=0 when you created the load module.
2. If you are calling ISPLINK, how are you getting addressability to it?
3. It could be a storage overlay.
4. or as you suggest, how do you set the pointers?
