Introduction to mainframe concepts with batch and online processing, data storage in file systems or databases, and COBOL/JCL basics for banking and billing applications.
Explore the basics of mainframe jcl, including the job statement, the exact statement, and the dv statement, plus how a Cobol program becomes a load module and runs.
Master the exec statement in jcl, covering job authorization, environment, and program execution options. Use time and region controls and condition or bypass to govern steps by return codes.
Explore how JCL utilities manage data sets and the GDG base, including creating and deleting datasets, handling duplicates, and implementing daily, weekly, and monthly generations with system-generated file names.
JCL - Job Control Lang, in Mainframe JCL is used in Batch application where all the logical programs coded in COBOL are compiled and executed.
In This Course we will Learn JCL - from basic to expert level. Perfect for interview and good for knowing how project use JCL.
