Collisions are now easy to avoid with _globals, but listing the _globals I've used here.
"ID", for example, is probably not a good label here, as it is too general. but I got here first, so don't use ID...
for VCA's
_global.ID
_global.slaveset
_global.resetoffset
for hardware router
_global.hardwaresel
_global.outonelev
_global.outtwolev
_global.outrestlev
(future) recording setup delay
_global.isp
