Exit Switch or break switch question

Hi Len,

Multiple exit points seems like a good point for clarity unless maybe  
the switch is very very long then you would know if one was found it  
would be the absolute end of the script instead of the possibility of  
it finding another match as well later on in the script.

However, with that said, this is a combo box and I would think only  
one choice can match so the break seems to be my answer for both  
clarity (smaller script) and few keystrokes and because no other  
matches are possible anyway.

Thanks,

Tom McGrath
