Understanding EXFMT in RPGLE
In this video, viewers gain insights into the EXFMT operation code used in RPGLE programming on the IBM i (AS/400) platform. The EXFMT operation is crucial for handling record formats in RPGLE, particularly when working with display files and database files.
In this video, viewers gain insights into the EXFMT operation code used in RPGLE programming on the IBM i (AS/400) platform. The EXFMT operation is crucial for handling record formats in RPGLE, particularly when working with display files and database files.
- Definition of EXFMT: The EXFMT operation displays a record format on the screen and reads user input back into the program. It effectively combines the functionalities of both DISPLAY and READ operations.
- Usage Context: The video discusses scenarios where EXFMT is applicable, such as in interactive programs that require user input and feedback.
- Record Formats: An explanation of how record formats are defined in DDS (Data Description Specifications) and how they relate to RPGLE programs is provided.
- Example Code: The presenter showcases sample RPGLE code snippets demonstrating the implementation of EXFMT, including error handling and validation techniques.
- Best Practices: Tips on using EXFMT effectively, including considerations for screen design and user experience, are highlighted.
- Common Pitfalls: The video addresses common mistakes programmers make when using EXFMT and how to avoid them.
