I do not know all of the details, but the idea is that in SAS 9.2, we will have the ability to surface dynamic and cascading prompts.
By "dynamic", I mean that the values will be automatically populated at run time, possibly from metadata and/or SAS tables, stored processes, etc.
"Cascading" means that the selection in one prompt affects, or cascades to, another prompt.
A typical example showing both of these features would be a variable selector. First, a "library" prompt is dynamically populated with a list of available SAS libraries. Once you choose a library, a "table" prompt is updated to display the list of tables in the library. Finally, once a table is chosen, a "variable" prompt displays the variables in the given table.
It is a work in progress so what I said above may not be exactly correct.
