This appendix is meant as a learning aid to show the relationships between COBOL and some syntax and object-oriented semantics of Java technology for those COBOL programmers without C, Pascal, or C++ experience. The assumption is that you have been through or are going through an object-oriented programming tutorial or course. The following topics are covered:

• Program organization
• Variable declarations
• Data aggregates (records/objects)
• Arrays
• Scope Overriding and this
• Assignment
• Displaying results
• Calling subprograms/methods
• Symbol visibility

For your convenience, a quick reference guide is provided at the end.
