Stack Directory?

[Ken Ray]

Sorry, I forgot to answer Chipp's other question:

No, unfortunately it is a requirement of MC to declare local variables
you're going to use in a matchText, matchChunk, or replaceText expression.
Honestly, I wish I didn't have to declare them; it would be so much easier
if MC would just create the variables for you...
