TDS_ES35G Advanced Assembler Language Coding Workshop
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.Virtual Learning
This interactive training can be taken from any location, your office or home and is delivered by a trainer. This training does not have any delegates in the class with the instructor, since all delegates are virtually connected. Virtual delegates do not travel to this course, Global Knowledge will send you all the information needed before the start of the course and you can test the logins.
COURSE OBJECTIVE:
After this course participants should be able to:
• 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
TARGET AUDIENCE:
This advanced course is designed for application programmers and beginning system programmers who code, maintain, and debug application support programs or subroutines written in S/390 assembler language.
COURSE PREREQUISITES:
Prior to attending this course, you should be able to code and debug simple S/390 assembler language programs.
