The notion of the this variable in the Java programming language, referring to the
target of a message send, has a few analogs in the COBOL world.
In COBOL, the record buffer associated with a file is sort of a
"cursor" or "current record" buffer that changes as you read through
the file. If you walk through a list of Java objects, sending them
each a message, the this variable will refer to each of the
objects in turn just like the moving file cursor.
The ambiguity resolution or scope override ability of the
this variable also has an analog in COBOL. When you have two
items in two different tables or files with the same name, you must
use the OF clause to indicate which one you are referring to
such as StudentName OF StudentFile.
