COBOL Programming Part 2

Summary: suitable for the bcs mainframe technology professional exams for level 1 developer
audience: application programmers with some experience in cobol who want formal training in the advanced language features and programming techniques.
Prerequisites: attending our cobol programming part 1 course or equivalent knowledge is assumed.
Duration: 5 days. Hands on.
Objectives: this class is designed for students to improve their knowledge of cobol tools. Each student will write, execute and debug cobol programs that stress the advanced features of cobol. This will include multi-dimensional and variable length tables, multi-program and sub-program calls, and vsam file manipulation. Sorting, merging and programming standards and style will be addressed.
