I had the great pleasure of meeting Brian Rusch in Milwaukee last month, when I spoke to the Wisconsin Midrange Computer Professionals Association (WMCPA). Brian told me about the method his shop uses to handle CL program exceptions. I’d like to share it with you.
IBM has established an architecture for exception handling. When a program exception occurs, the system may send one or more diagnostic messages that give information about the error. The system does send an escape message, which summarizes the problem and cancels the program.
