An indirect page reference is a page reference that starts with the keyword prompt followed by the page name. Unlike an explicit, fully qualified page reference, the system finds indirect pages by searching the clipboard at runtime.
With a Call or Branch instruction, the calling activity can identify parameters to the target activity using indirect page references. For example, if you identify a page as promptALPHA, the system searches the clipboard for pages named ALPHA.
You cannot use symbolic page names (such as primary or param) after the keyword prompt; an explicit page name is required.
You can use indirect pages in these rule types:
On the Pages & Classes tab of these forms, indicate that a page referenced in the rule is an indirect page by setting the Mode field to prompt.
