When setting the passKey of a protected stack, is there a way to catch

for me to try one, then if it fails try another, I'd be a lot happier
today! My guess is that it can't be done, but maybe?
In earlier versions of Rev you could check is a stack is protected with
this:
return (the passkey of stack tStack = the password of stack tStack)
...to return true if the password had never been set or if the passkey
has been entered during the current session.
Unfortunately this broke with the new, more secure, method of encrypting
scripts in v4.0.
Now the only reliable method I've found also works in earlier versions
but is a little longer, requiring a try/catch block:
function IsPasswordProtected pStack
try
get the script of stack pStack
catch tErr
return true -- couldn't get script
end try
return false -- got it OK
end IsPasswordProtected
You can use a similar try/catch setup to attempt to set the password,
with the catch part coming into play if it fails.
