No whichMenu. ??? I don't know where to look to find out where the

anyone know where whichMenu is described?
It looks like a passed parameter variable is showing up in the
message watcher. When you write a menuPick handler you normally want
to include a parameter variable after the handler name, like this:
on menuPick whichMenu
switch whichMenu
case "Open"
# do open stuff
break
case "Quit"
# do quit stuff
break
end switch
end menuPick
The parameter variable holds the name of the menu item that was
chosen. It can be any valid variable name, but many rev programmers
use the convention in which parameter variables begin with p, eg.
pWhich or pTheThingTheyChoseOnTheMenu. You really need to capture
this passed argument in order to make the menu behave the way you
want. If it's not captured in a variable then the menuPick handler
likely will not work.
