•	Name, code, and description of the operation.

•	Parameters—a table indicating which of the six parameter values the operation expects from and returns to your application. A “Sent” parameter is sent from the application to the operation; a “Returned” parameter is returned from the operation to the application when the operation is complete.

•	Prerequisites—the conditions your application must satisfy for the operation to be successful.

•	Procedure—the steps for initializing the parameters that the operation requires.

•	Details—additional information about the operation.

•

Result—the results of both a successful and an unsuccessful operation. Each operation returns a status code, informing your application of the outcome of the operation. Status Code 0 indicates the operation was successful. A nonzero status code usually indicates a failure. However, some nonzero status codes are informative and appear even when the associated operation is successful—for example, Status Code 60 means the specified reject count has been reached.

•	Positioning—the effect the operation has on the logical and/or physical currency of the records in a file.
