Description

This programming assignment does not require any further coding or documentation than what is provided. The program will ABEND and your task is to learn how to investigate what happened so that you can debug your own Assembler programs in the future. To begin, run the following program on the Marist mainframe using the ASSIST JCL used previously. Be sure you type it or copy it EXACTLY as shown below:

Use the resulting ABEND dump output to answer the questions below. Each is worth 2 points except question 11 which is worth 5 points.
1. Did this error occur (a) while the program was being assembled or (b) when it was being run?
