This course is for students who must understand and code Data Language/I (DL/I) to access segments in IMS/VS databases.
Mainframe Training Prerequisites
A familiarity with conventional file organizations for sequential and direct access to data records is needed. Six months of experience with COBOL and JCL is required. Also, the completion of an Introduction to IMS/VS class or equivalent experience is recommended.
