• 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

presentation, discussion, hands-on exercises

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.
