This is the third course of a multi-part series that teaches the basics of Enterprise COBOL application development. It focuses on multi-module programs using CALL and LINKAGE SECTION, internal SORT, Variable blocked record processing, STRING, UNSTRING, INSPECT, more intrinsic functions, LE functions and XML parsing and generation.

Skills Gained

As a result of taking this course, you will be able to:

  • Code main and subprograms and call subprograms from other programs, passing appropriate data
  • Pass data from JCL PARMs into your main COBOL program
  • Process VB records
  • Code internal SORTs and use a variety of advanced SORTING techniques.
  • Generate XML documents and parse XML documents (optional)


Students need to have completed the Enterprise COBOL Programming: Intermediate course, and have basic experience with z/OS JCL for JES2 or JES3, and TSO/ISPF.

Concise and good to follow along. Although it is a lot to take in under a short period of time.

Fantastic and great training. Tons of hands-on labs to really make you understand the material being thought.

Labs and the study materials provided for Architecting on AWS course are very easy to understand and explains all the topics required to pass the Associate certification.

The labs and course material gave me valuable insights into cloud security architecture

Great company -- easy to sign up and very organized. Loved my teacher and class overall.
