7.8 BROWSE
| Note | ||
|---|---|---|
| title | Note | : Usage options |
The BROWSE command is used to display selected fields from selected file records at a workstation.
...
The use of the BROWSE command in new applications is not recommended.
The BROWSE command was provided in an early release of LANSA and it will always exist for that reason.
However, subsequent releases of LANSA have included features like application templates, pop-up windows, and prompt key processing that far exceed the speed and functionality of the BROWSE command.
The BROWSE command cannot be used in programs that are portable. Use the *DBOPTIMIZE facility, request multilingual support, and GUI (Graphical User Interface) enabled or Web-enabled.
Portability Considerations | A build warning will be generated if used in Visual LANSA code. An error will occur at execution time. Code using this facility can be conditioned so that it is not executed in this environment. |
