12.3 Considerations for Browse Lists

When working with a browse list for a LANSA Web function application, you must adapt your thinking to the browser paradigm. Consider some of the following points.

  • What works in the 5250 environment may not work on the Web.
  • Extending the browse list makes it longer and longer in LANSA for the Web.
  • The concept of "page at a time" in the 5250 environment is not the same for the browser.
  • You should consider building browse lists to contain just ONE page and work with the contents of that single page as it is displayed to the user.
  • Consider using "position to" logic so that only the relevant records are retrieved and displayed. Using "position to" logic is a much better solution than having the user either scroll through huge lists or page forward through screen after screen.
  • Also, WEBEVENT functions do not support the use of a list with *SELECT field.
