Re: [mv] [if] and its ilk

I don't think the syntax you presented is right..
You might want to try
[if value some_val ne ""] something [/if]
Minivend doesn't support expression negation (as far as I know), but
instead implements a specific operation (in this case for ne) for
handling the not equal cases.
