In a lecture/workshop environment the participant is taught practical programming skills required to function as an entry-level programmer in an IBM Enterprise COBOL mainframe environment. Structured COBOL design and coding techniques are emphasized throughout the class. Common mainframe programming scenarios and problems are presented and reinforced through a series of hands-on workshop problems. Access to a working TSO/zOS system is required for student workshop sessions. Students should be ready and willing to devote some time before and after class hours to completing workshop problems. Existing company standards and coding conventions can be integrated into this class.

During a week, the topics for that week may be intermixed to enhance or reinforce the learning experience of the participant. e.g. Some of the JCL topics may be taught in the context of the relevant zOS and COBOL topics. One should not infer that a topic indicated for a specific day of the week will be the only topic for that day. Experience has shown a student understands a topic or concept better when taught in context of related topics and utilized in that context rather than as a standalone topic.

This training will provide the participant with the fundamental, essential skills to function in a mainframe COBOL environment as an entry-level programmer. Additional training will be required for specific skill areas of mainframe processing based on the position the participant will be assuming. Although an introductory overview of VSAM, DB2 and CICS is included in this class, students will required specific training in those areas in order to acquires the skills necessary to utilize them effectively in a role as Application Developer. Participants will benefit from follow up training in I.T. soft skills and a more in-depth presentation of some topics.
