    Launch course

    This course provides instruction and practice in the use of the more complex S/390 Assembler Language facilities for the experienced assembler language programmer. The course includes a discussion of standard linkage conventions, use of BSAM/QSAM and selected system macros, the macro definition language, and reentrant coding considerations. Emphasis is placed on enhancing skills in problem resolution through analysis of more complex system-provided dumps.

    Objectives
    • Identify data management considerations and access methods
    • Code assembler language programs which:
      • Conform to standard linkage conventions using save area chaining
      • Define and use BSAM/QSAM datasets through standard I/O macros
    • Define and execute user macros which contain:
      • Positional and/or keyword parameters
      • Fixed or variable entry parameter lists
      • Conditional assembly logic
    • Use variable length storage operations (that is, EX, MVCL, and so on)
    • Employ more complex instructions (that is, TR, TRT, BXLE, and so on)
    • Access JCL parameter data
    • Employ LE date/time handling services
    • Identify reentrant coding considerations and dynamic storage acquisition
