/**

* Use the AS400FileRecordDescription to create static objects which represent

* the external definitions of the model input and output data structures

* (MDLIDS01 and MDLODS01). Run this after changing the structure of either

* physical file which externally describes these data structures.

* <P>

* From the javadocs of AS400FileRecordDescription:<br>

* The AS400FileRecordDescription class represents the record descriptions of a

* physical or logical file on the server. This class is used to retrieve the

* file field description of a physical or logical file, and to create Java

* source code for a class extending from RecordFormat that can then be compiled

* and used as input to the AS400File.setRecordFormat() method. This allows the

* record format to be created statically during development time and then

* reused when needed. The class also provides a method for returning

* RecordFormat objects that can be used as input to the

* AS400File.setRecordFormat() method. This method can be used to create the

* record format dynamically.
