Description

This course teaches how to code advanced CICS application commands in a COBOL program. The lectures cover menu-driven applications, paging transactions, on-line printing using the CICS/JES spool interface, field-level help, system information, automatic transaction initiation, and other advanced topics. Hands-on exercises reinforce the concepts.
