SUMMARY:   Suitable for the BCS Mainframe Technology professional Exams for levels 1 and 2 Developer, level 2 Engineer (Data Storage) and level 3 Consultant (z/OS) AUDIENCE:   System Programmers, Technical Support and Software Programmers and Advanced Application Programmers who need the ability to write and debug Assembler Language programs and better understand the software that their installation uses. PREREQUISITES:   When attending this Advanced Assembler course, the assumption is that the delegate attending will be very familiar with the instruction set as outlined in the first Assembler course. The course includes all the new instructions that IBM has made available. Most of the course time will be handling the remaining instructions that were not discussed in the first course and the new instruction set. DURATION:   4 days. Hands on. OBJECTIVES:   After completing this course students should be able to: Develop a better understanding of the machine and how it processes instructions. Develop the skill to write assembler programs, particularly those small functions which will increase the efficiency of their corporation's computing throughput. Gain a practical introduction to the essential operating system interfaces with Assembler. Enhance their diagnostic skills. Improve their dump analysis skills. Enhance their ability to use advanced management services. Enable themselves to code their own macro definitions. Enhance their knowledge of Channel Programming and how it works. Improve their programmers design abilities.
