form action

Interchange "form actions" are basically Perl subroutine definitions that you can execute upon form submission. Which form action to trigger is specified by the mv_action form variable.

Successfully executed form action should return a true value, upon which Interchange would display the page specified in mv_nextpage. If the form action returns false, Interchange will not display any page.

Using FormAction, you can both define new and override existing form actions.
