Alan:
You have probably figured this out by now
(having a long, quiet weekend without the listserver)

In order to call a function or procedure in an include
file, you have to make it visible to the program that
"includes" it:
-----------------------
--howdy.e
global procedure SayHi()
atom x
  x = 5 * 2
  printf(1,"Hi! Did you know the value of x is: %d ?",x)
end procedure

-----------------------
--main.ex

include howdy.e

SayHi()

------------------------

And yes, you can declare variables within a function or
procedure! In fact, you should generally do that. Global
variables should be very rare, if you want code that
is easy to follow, and doesn't break.


That's all, folks!
