How much do callbacks to HyperCard from externals slow the execution
of an Xternal.  I'm not looking for exact measurements just an overall
feeling.  Along the same lines is it faster to execute HyperTalk
commands from within a script of is it faster to make callbacks
from the Xternal's code?

Thanks
