MiniVend treats some form fields specially, to link to the search engine
and provide more control over user presentation. It has a number of
predefined variables, most of whose names are prefixed with mv_ to prevent name clashes with your variables. It also uses a few variables
which are postfixed with integer digits -- those are used to provide
control in its iterating lists.
Most of these special fields begin with mv_, and include:
(O = order, S = search, C = control, A = all, X in scratch space)
