Dumb newbie back in shell

[MartinRinehart at gmail.com]

Peter,

question is, why did the first one work? In my real code I've got
module-level vars and an error msg trying to use them in a function.
In my test example I've got them accessed from within a function w/o
error message.

I am confused.
