Re: consistent way to check for existence of member

[Valentin Schmidt]

Thanks everyone for the answers. I just wrote exactly the same mail as 
Cole did (starting with the "Looks like ..." part omitting the showers 
:-), but Cole was faster.

Here's the obvious/ugly way that you probably would like to avoid:
on memberExists (someName)
  if the scriptExecutionStyle < 10 then return
(member(someName).membernum > 0)
  else return (not voidP(member(someName)))
end

Now I feel like taking a couple showers!

Looks like Tom's got the best approach:
on memberExists name
  tMemRef = member(name)
  if voidP(tMemRef) then return FALSE
  else return (tMemRef.number > 0)
end
